Is a deflated ball heavier?
A deflated football has a smaller mass because it has fewer gas molecules inside of it. Assuming that the temperature is 32 degrees Fahrenheit (0 degrees Celsius), the mass of the air in a football inflated to 12.5 psi is about 0.39 ounces (11 g). A football deflated to only 10 psi has a mass of 0.36 ounces (10.2 g).
Does an inflated ball weighs more than a deflated ball?
Depending on the pressure that the ball was inflated to, the density of the fluid inside the ball would also change. Once the pressure inside the ball increases above 101.3kpa (given that the ball doesn’t deform), the apparent weight will be more than the uninflated ball.
Which is heavier The inflated or the deflated Why?
Answer: Inflated balloon is heavier because it has the weight of the balloon skin and the air inside. This makes it heavier because air has mass. … The pressure caused by stretching the balloon envelope increases the density of the air inside, thus adding to the weight.
Why is an inflated ball heavier than a deflated ball?
WHENEVER WE SEE AN INFLATED BALL AND A DEFLATED ONE, MASS OF THE INFLATED ONE IS MORE BECAUSE THE ONLY DIFFERENCE BETWEEN THE INFLATED AND DEFLATED IS THAT INFLATED HAS AIR IN IT WHEREAS THE DEFLATED DOESN’T HAVE.
Are NBA balls heavier?
NBA basketballs, according to USA Basketball, are 29.5 inches in circumference while the WNBA’s basketballs have a maximum circumference of 29 inches. Both should be inflated to between 7.5 and 8.5 pounds per square inch.
How heavy is an American football?
A regulation football is 28–30 cm (11–12 in) long and 58–62 cm (23–24 in) in circumference at its widest point. It weighs 410–460 g (14–16 oz) and is inflated to 65.7–68.8 kPa (9.5–10.0 psi).
Does air have weight?
Air does, in fact, have weight, and here’s a simple way you can prove it. You’ll need two identical balloons, a string, and a dowel. … The side with the inflated balloon hangs lower than the other side. You have demonstrated that air has weight!
How much is a basketball inflated?
An NBA regulation ball is inflated to between 7.5 and 8.5 psi. By regulating a basketball’s air pressure, the NBA can ensure fair playing conditions.
