Q:

Does a hot tennis ball bounce higher?

A:

Quick Answer

Because higher temperatures result in higher pressure, a tennis ball bounces higher when it is hot. When the gas molecules expand in the tennis ball, it causes more energy and a higher bounce.

Full Answer

When the temperatures decreases, it has the opposite effect on the tennis ball's bounce. The gas molecules contract and move around much more slowly. In the winter season, tennis players often string their rackets 2 pounds lower to compensate for the change in pressure in the tennis ball. A fully inflated tennis ball often appears deflated or softer if there is a sudden change in temperature outside.

    How do hot air balloons work?

    A:

    Hot-air balloons work based on the principle that hot air is lighter than cool air. By using a propane burner that heats the air inside the balloon, the air inside the envelope, or the top part of the balloon, becomes lighter than the surrounding air, causing the balloon to rise.

  • Q:

    How does a hot air balloon fly?

    A:

    A hot air balloon can fly because the heated air inside the balloon is lighter than the colder air around it. The more dense and cold air beneath the balloon apparatus pushes it upwards into the air. The construction of a hot air balloon consists of a large balloon envelope, a burner that requires propane fuel from a tank, parachute valve and a basket.
