What I Can Do
Let's bring Charles' Law in action by giving solution to the following problems:
1. Pump up your ping pong ball.
If you play ping pong possibilities are you've come across the occasionally dented
ball. How will you restore its roundness?
2. Baking
We can see Charles's law in our kitchens also. Using a yeast as an ingredient,
how is the law applied in delicious bakery products like bread, and cakes?
3. Deodorant Spray Bottle
Have you read the cautions written in the deodorant bottle? They suggest storing
it below 50°C and also warn to keep it away from direct sun light and ignition.
How can you explain this using Charles' law?

We can see Charles's law in our kitchens also. Our delicious bakery products like bread, cakes would not be spongy and soft without yeast. Yeast is a leavening agent belonging to fungi. It converts sugars in the dough to carbon dioxide gas. When bread and cakes are baked, this conversion is accelerated. The gas liberating expands because of high temperatures in the oven. Ans this expansion gives bread and cakes spongy appearance.

pingpong balls

A common problem with ping-pong balls is they can get a dent when expose to a strong blow or pressure. A common method to fix this dented ball is to immerse the ball into warm water. On immersion, the temperature of the air inside the ball increases, and as per Charles's law, the air expands. The ball is inflated and dents are fixed.

deodorant spray bottle

If you get a chance to read the instructions on a bottle of deodorant, you might have read the warning signs indicating the bottle to be kept away from the sunlight and high temperature. Ever wondered why? The answer lies in Charle’s Law. Under high temperatures, the air molecules inside the bottle will expand which can lead to the bursting of the deodorant bottle.
