Chan Hee is inflating a basketball using an air pump. He notices that the pump gets warm as he uses it. What is a good hypothesi

s that could lead to new experimentation?
If there is no air in a basketball, then it is hard to play the game.
A basketball that is inflated bounces better than one that is not inflated.
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Basketball is more fun to play than baseball because you have to move a lot more.

"If air in a pump is squeezed more, then the air gets hotter because energy is added to it" is a good hypothesis that could lead to new experimentation.

<u>Option: C</u>

<u>Explanation:</u>

If we use a pump to inflate a basketball, we initially pull the handle to draw air to fill the sphere in. As we move it down we apply a great deal of force to pump in air through the pin's tiny hole because of this resistance force in the air we find the tube warmed.

A needle of ball pump is a metal tube in which air, from an inflating pump to a sports ball, moves through it. In continuous-flow operation, pumps are often used and built to produce comparatively little pressure towards a free-flowing environment with limited back pressure. Such pumps have a fixed configuration and work freely along their power curve as circumstances change.
