Why does putting a dented ping pong ball in boiling water remove the dent?
Explain why placing a dented table tennis ball in a boiling pot of water is one way to remove a dent in the ball. The boiling water would be the temperature increase. This would increase the volume of the ball which would make the size of the ball get bigger. The increase would get rid of the dent.
What happens when the gas in a dented ping pong ball is heated?
Ping pong balls contain gas inside them. When a ping pong ball is dented, it can be fixed by heating the ball in a pot of hot water or any other safe process that causes heat. The gas inside the ball gets heated up and expands, pushing the dent out and making the ping pong ball functional again.
What happened to the ping pong ball when submerged in hot water?
A ping-pong ball has been dented . . . so you put it in hot water. The dent is an intrusion into the volume of the ping pong ball, so if you could just get the volume of the ping pong ball (the gas within) to increase, then you could get rid of the dent.
What happens when you drop a ping pong ball?
Ping Pong Ball Blast-off! When you drop a ball on the ground you probably expect it to bounce. If it’s a really bouncy ball it might rebound almost back up to the height from which you dropped it (scientists would say that the collision with the floor is elastic, or the ball has a high coefficient of restitution).
How do you fix a dented ping pong ball without water?
Simply hold the ping pong ball in the towel and point the hairdryer at it on a high heat. This has same affect of heating up the air particles inside the ball causing the pressure to change and pop the dent out.
How do you fix a broken ping pong table?
How to Repair a Ping-Pong Table Surface
- Like Putty in Your Hands. Remove the net from the table.
- Sand and Smooth. Sand the tabletop by hand using 180-grit sandpaper.
- Rattle Cans. Aerosol cans are fine for repainting the table.
- Tape It. Use painter’s tape to mask off the lines around the perimeter and along the sides.
When you let your ball float on hot water?
When you let your ball float on hot water, the temperature of the air inside the ball also increases; which, in turn, leads to an increase in the volume of the gas. Therefore, the shape of the ball is restored.
Does a ping pong ball fall slower?
Terminal velocity is achieved when the forces balance. Weight is the accelerating force and air resistance is the decelerating force. Air resistance is a function of air density, cross sectional area, coefficient of drag and velocity squared.
How do you fix a water damaged ping pong table?
Apply a very thin coat of the wood putty over the damaged areas; smooth and feather it at a sharp angle with the spatula. Allow this to dry completely before proceeding. Sand down the wood putty to the level of the playing surface. Smooth and feather in the wood putty with the finest grade of sandpaper.
