It fixes the dent because the heat from the boiling water makes the air inside the ping pong ball expand, causing the dent to be filled out.
The heat cause the air inside the ball to expand and undent the ball
The heat will cause the air inside the table-tennis ball (ping pong ball) to expand and so push the dint out.
Put an exact amount of water in a measuring cup. Drop in a golf ball. The increase in water level equals the volume of the golf ball, assuming the ball doesn't float. For example, 200mL before ball. 280ml after ball dropped in. Therefore volume equals 40ml or 40 Cubic Centimeters.
The diameter was 26 cm.
If they float in water, then it is because the density of a ping pong ball is lighter than the density of water. The density of water is just below 1, and the density of a ping pong ball is much less than 1.
The heat cause the air inside the ball to expand and undent the ball
Placing a dented table tennis ball in boiling water causes the air inside the ball to expand, pushing out the dent and restoring the ball's shape. The heat softens the plastic material of the ball, allowing it to return to its original state. Once the ball cools down, it retains its new shape.
Placing a dented tennis ball in boiling water causes the air inside to expand, pushing out against the dent and restoring its shape. The heat softens the rubber on the ball, making it more malleable and allowing it to regain its original form when the pressure is released.
The heat will cause the air inside the table-tennis ball (ping pong ball) to expand and so push the dint out.
The hot water causes the air trapped inside the ball to expand and it may pop the dent out to the original shape.
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 hot water heats the air inside the ball, which expands and forces the dent to pop out.
boil it in water, the dent should rise back up unless there is a crack
ping pong ball
If you put a dented ping pong ball in ice water, the cold temperature may cause the air inside the ball to contract, intensifying the dent. Additionally, the change in temperature can affect the elasticity of the ping pong ball material, potentially making the dent more permanent.
Weigh it down some how in water and boil the water,or you may also use the butt of a racket and round the ball back up
As the internal air is warmed it expands and pushes out the dint.
