This is a method to repair a dented ping pong ball.
ping pong ball
The hot water will soften the ping pong ball, causing it to regain its original shape as the material becomes more pliable. The dent should eventually pop back out as the ball absorbs the heat and expands.
The inside of a ping pong ball is empty, and the skin is made of celluloid. A common problem is that the ball is easily dinted. To remove a dint in the ball's surface, place the ball in hot water. The air inside expands on heating and pushes the dint out.

Yes. The hot water will make the air inside the ball expand, removing the dent.
The heat softens the ball and, unless the ball is cracked, the pressure increase from the air inside the ball being heated causes a small dent to pop out.
The heat from the boiling water warms up the air inside the ping pong causing the air to expand and push the dent of the ping pong back out.
the heat makes the air expand inside the ball, which in turn would make it "blow up" back to its original shape
Because heat makes plastic expand in hot water.
Anemometer's have two classes, some are used to measure wind speed while others are used to measure wind pressure. There are severl kinds of anemometers ex. Cup anemometers, windmill anemometers, Hot-wire anemometers, Laser Doppler, Sonic, And Ping-Pong ball anemometers.
