Your question: How heavy is a deflated basketball?

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.
