Using the Allen key provided undo the grub screw until gas can be heard escaping. (c) Pump more gas into it. (a) Put it into a refrigerator. Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure. (Please use the absolute pressure in the ideal gas formula) You need to fill up a basketball thats low on air pressure. (a) Put it into a refrigerator. How to fill air to basketball, volleyball, football, without pumpplease watch full video A mixture of nitrogen (78%), oxygen (21%) and trace gases. It depends on how you define the Basketball. The amount of air in the ball determines the amount of air pressure present. an inflated because it takes up more room than a deflated one. NBA recommends that the air pressure in a basketball must be between 7.5 and 8.5psi. 8y. This problem has been solved! Basketballs, along with other objects such as tires and footballs, are high-pressure products. This means that they require a lot of the force created by air pressure in order to get and stay fully inflated. There are various measurements used for air pressure. Hook the other end of the tube to your can of compressed air. When a filled balloon is squeezed, the volume occupied by the air inside the balloon decreases. Add Tip. You may apply the reverse for the release of air from the cylinder. (Please use the absolute pressure in the ideal gas formula) You need to fill up a basketball thats low on air pressure. To put this all in to context for you, 1 cubic foot of natural gas is enough to fill a basketball, and 1,000 cubic feet (1 Mcf) of natural gas is approximately enough to meet the natural gas needs of an average home for five days, and that includes space-heating, water-heating, cooking, etc. If you define it as just the rubber, then the mass does not change when it is inflated. Insert the hose barb on the other end and push it on, It won't need a clamp due to the barbs on the inside of the tube.Put some olive oil or pam on the stem and push that in and secure it with the clamp. Which method below changes its volume because of a mass change of the gas inside? Will the needles work with the local gas station's free air pump, which has a hose chuck and a digital readout so you're adding exactly as much PSI as you need? The volume of the ball is 7000 cubic centimeters, and you can assume that the volume of the ball remains constant as you pump air into it. 2. 1 trillion (1,000,000,000,000) cubic feet = 1 Tcf. You need to fill up a basketball that's low on air pressure. Be careful not to oversaturate the ball. In our Tennessee Lady Vols Forum you can discuss Lady Vols Basketball, Lady Vols Softball, or any other Tennessee Lady Vols athletics. The absolute pressure of the air (assuming it is inflated near sea level where ambient pressure is: 1 atmosphere = 14.5 lb/in 2, or = 101325 Pa in SI units) is therefore ~22.5 atm ~= 152000 Pa. A gas exerts a pressure of 3 kPa on the walls of container 1. How to inflate a basketball with a basketball needle, and the Ultimate Speed UMK10 B2- Air Compressor from Lidl. (d) Hold it under water. The massive gas shortage that arose after a major U.S. pipeline's computer system was hacked took the East Coast by storm earlier this month. Find more details like Charles law formula, derivation, application in this page. This might be a more expensive option if you use compressed air regularly, but it can be used to inflate a basketball. The little straw that fits onto the cannister should also fit inside the basketball. Use small blasts of air to fill up the ball. This will only work if you have enough compressed air to fill up the ball. In winters as the temperature decreases, when you take a basketball outside in the ground the ball shrinks. Its initially at a gauge pressure of 6 psi, and you want to inflate it to 7 psi so that it is properly inflated. Best to use for: If you are without a needle and pump, a can of compressed air is probably the quickest and easiest way to fill up your ball. This will only work if you have enough compressed air to fill up the ball. Which method below changes its volume because of a mass change of the gas inside? Or is there any other way to fill this ball besides buying a pump or a compressor? 1. Air is composed of different gases, including nitrogen, carbon dioxide, water vapor, oxygen, and others. I have a deflated basketball, inflation needles, but no compressor or pump. Given, Initial pressure, P 1 = 3kPa. U c v = H i n > 0, so T > 0. Reply #1 on: 26/05/2005 15:05:19 It would bounce slightly higher for two reasons: The helium is lighter than air so the ball will have slightly more uplift for it's weight so feel like it was in less gravity - so bounce higher (if you throw it at the ground at the same speed rather than drop it from a height). Start pumping air into the ball. Mass is "stuff". Tennessee Lady Vols. Assume that the temperature and quantity of the gas remain constant. The good news is, the gas supply chain is finally starting to get back to normal, so if you live in one of the affected states, you probably are no longer having a problem finding gas these days. In general, the higher the air pressure is inside the basketball, the higher it will bounce. According to Boyles law, V 1 = (P 2 V 2 )/P 1. Replies 253 Views 58 minutes ago Dan. Air pressure, simply put, is the push that air has against all surfaces that it touches. The more air there is in a contained area, the greater the air pressure. Specifically, we'll try to determine what amount of air pressure in a basketball makes the ball (and hopefully the person using the ball) perform best. They tested this on Mythbusters with kicking a football. Find step-by-step Physics solutions and your answer to the following textbook question: You have a basketball filled with gas. It offers you something very similar to the needle, so Basketballs are inflated with air to make them bounce. It's initially at a gauge pressure of 6 psi, and you want to inflate it to 7 psi so that it is properly inflated. Method 1: Use a Can of Compressed Air. Air has mass because air is stuff. (e) Leave it in the sunshine.. Please read before adjusting or mounting the gas struts. (c) Pump more gas into it. Will the needles work with the local gas station's free air pump, which has a hose chuck and a digital readout so you're adding exactly as much PSI as you need? It's easier to get a sense of air and air pressure when you think of air that is contained within something, such as your basketball, an air mattress, or a bike tire. Dan. You can use this standard measurement as a guide to get the required air pressure for your basketball. The air pressure of a properly inflated basketball is ~8 lb/in 2 gauge pressure, meaning pressure relative to the surrounding atmospheric pressure. What type of gas is a basketball filled with? NIL Thread (Name, Image, Likeness Rule) Dan; May 1, 2022; 9 10 11. Therefore, the enthalpy of the gas which you are filling adds to the internal energy of the gas in the cylinder, and because the internal energy is positively correlated to temperature, the temperature in of the gas in the cylinder rises. The internal pressure of a gas strut is very high and should be treated with caution. This is accompanied by an increase in the pressure exerted by the air on the balloon, as a consequence of Boyles law. (b) Squeeze it. A quick way to check if your ball has the proper air pressure is by taking this simple test. Find step-by-step Physics solutions and your answer to the following textbook question: You have a basketball filled with gas. GasBuddy provides the most ways to save money on fuel. (b) Squeeze it. Final pressure, P 2 = 6kPa. Cut about 2 -3 off your tube slide one clamp on the side you want the valve to be on. You can inflate your basketball at a gas station, but you probably wont be able to do so without a needle. So within the context of this guide, pumping your ball at a gas station isnt an option. But if we were talking about pumping balls without a pump, then it would work. The little straw that fits onto the cannister should also fit inside the basketball. Heres how you should use a can of compressed air to inflate a basketball: Insert one end of the tube that comes with the can into the balls air hole. If a ball is not inflated fully, it will bounce low and erratically. This might be a more expensive option if you use compressed air regularly, but it can be used to inflate a basketball. Final volume, V 2 = 10L. Its initially at a gauge pressure of 6 psi, and you want to inflate it to 7 psi so that it is properly inflated. Please note that cleaning could affect ball performance or feel. Or is there any other way to fill this ball besides buying a pump or a compressor? V 1 = (6 kPa * 10 L)/3 kPa = 20 L. Therefore, the volume of container 1 is 20 L. Today's best 10 gas stations with the cheapest prices near you, in Greenfield, IN. (d) Hold it under water. Use small blasts of air to fill up the ball. Step 4: Cut Your Tube and Attach Everything. Find the volume of container 1. When inflated, the basketball's elastic bladder is capable of rebounding when dropped or dribbled on a hard surface. But the effects of the gas Gas struts are filled with high pressure Nitrogen and under no circumstances should they be opened or subject to excessive heat. Allow to air dry before using. Re: Helium filled basketball? I have a deflated basketball, inflation needles, but no compressor or pump. If you consider the air inside the ball to be part of the ball then adding more air adds more mass. Soap and Water Method: Dirt and debris can be removed by using a damp cloth with soap and water, using moderate pressure. (e) Leave it in the sunshine.. Just like the balloon in the previous experiment, basketballs and other sports balls are filled with air.
