Which gas law explains how the dent in a ping pong ball can be fixed by submerging it into hot water?
Charles Law Graph
That gas remains inside them unless they pop. 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.
How does a ping pong ball float in air?
The ball “floats” in the air at an even point when the force of gravity (which is forcing the ping pong ball down) is equal to the force of the air stream from the hair dryer (which is pushing the ping pong ball up). This is known as Bernoulli's Principle.
What makes a good ping pong ball?
ITTF-approved table tennis balls must weigh 2.7g. But there's an accepted tolerance of between 2.67 and 2.77g. Lighter ping pong balls are slower and more likely to wobble, whereas heavier balls are faster and more stable in their trajectory.
Are ping pong balls flammable?
Celluloid is a highly flammable substance, and since table tennis balls are made of celluloid, they burn up easily too.
Are ping pong balls safe for toddlers?
Remember that children under 3 can't cough things up. So if a toy is as small as a ping-pong ball, or can easily break into parts the size of a ping-pong ball (or smaller), then a child under 3 should not be playing with it.
What is a 40+ table tennis ball?
The reason the balls are labelled with 40+ is that when the ITTF made the plastic balls legal for competition, they also allowed the balls to have a bigger size tolerance. So a celluloid ball tends to be around 39.6mm whereas the new plastic balls measure around 40.2mm, making the plastic balls about 0.5mm bigger.
What is the difference between orange and white ping pong balls?
The difference between orange and white ping pong balls is the color. The right ball is chosen by looking at the playing environment and the athlete's clothing. If the area is light, it's best to choose an orange ball. If the area is dark, then a white ball is the best choice.

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.
What is gas law chemistry?
The law states that at a constant volume, the pressure of the gas is directly proportional to the temperature for a given gas. If you heat up a gas, the molecules will be given more energy, they move faster.
What is an example of Boyle's Law in real life?
You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
How do you get a dent out of a ping pong ball?
