Real life application for charle's law?

Answer 1

· The Ping-Pong Balls

Little children come up with ingenious ways of mending their toys. One of them is removing the dent from a ping-pong ball.

When a ping-pong ball gets dented without being punctured, the best solution is to dip it for a while in warm water. Since the air inside the ball tries to match the temperature of the water outside, pressure builds up as a result, popping the dented part back into place. This shows how an increase in temperature caused a proportional increase in pressure according to Charles Law.

· The Soda Can

Beer or soda cans and bottles have a label on them stating, "Store in a cool, dry place". The reason, being that these cans have a lot artificial pressure stored in them, is when exposed to direct sunlight or heat, the pressure inside the cans rise. However, since the volume is constant, the pressure increases to a limit where they burst, letting out all the pressure. The temperature increase in the can resulted in the increase in pressure, resulting in the explosion.

· The Balloon

Imagine a balloon filled with helium on a cold winter day. While you are in the shop, the balloon is normal. As you step outside the balloon begins to shrivel up. This happens because of the temp. of the helium in the balloon deceases and becomes less dense, because the helium particles lose energy and become more concentrated, decreasing the volume. But when you put the balloon in a warm area, it goes back to its original size.

· The Bicycle Tires

You go out one day on a winter day and ride your bicycle. After a couple of hours of travelling around the neighbourhood or the city, you noticed the tires are getting flatter even if there is no puncture mark on it. This happened because if the weather gets colder, the air in your bike tires will shrink in volume and they will go flat.

· The Hot-Air Balloons

When flying-hot air balloons, balloonists apply the principle of Charles' law. As the air inside the balloon is heated, its volume increases. The density of the air decreases as the air inside the balloon is heated; it expands, resulting in an increase in density of the air inside the balloon. The density of hot air is less than of cold air. The difference in density between the air inside and outside the balloon makes the hot-air balloon rise.

Answer 2

Charles law states that the volume of gas will increase as the temperature rises if the pressure remains constant. When baking bread, the yeast gives off carbon dioxide which expands during the rising temperature and cause the bread to rise.
