Here is a list of a few of the most popular and intriguing examples:īalloon flight – You must have seen a balloon in the sky at least once in your life. There are actually various areas where we can use Charles' law. This is a great example that shows us that we can use this kind of device as a thermometer! Well, it's not a very practical method and is probably not as precise as the common ones, but it still makes you think, what other unusual applications can you get from other everyday objects? We can write the outcome in the more amiable form T₂ = 336.5 ☌ or T₂ = 637.7 ☏. Let's apply the Charles' law formula and rewrite it in a form so that we can work out the temperature: With all of this data, can we estimate the temperature of our heater? After a few minutes, its volume has increased to 0.062 ft³.

Then we put it close to the heating source and leave it for a while. We can find that its initial volume is 0.03 ft³ at room temperature, 295 K. It's filled with nitrogen, which is a good approximation of an ideal gas. In the second problem, we heat an easily-stretched container. The result is sufficiently close to the actual value. One tiny remark – air is an example of a real gas, so the outcome is only an approximation, but as long as we avoid extreme conditions (pressure, temperature). Fortunately, it's only physics, so you don't have to buy another ball – just inflate the one you have and enjoy! The ball seems under-inflated, and somebody may think there is a hole, causing the air to leak. Sometimes you can experience that effect while changing your location or simply leaving an object alone when the weather turns. We can see that the volume decreases when we move the ball from a warmer to a cooler place. Then we can apply the Charles' law equation in the form where the final volume is being evaluated:

How does the volume of the ball change?įirst of all, the Charles' law formula requires the absolute values of temperatures so we have to convert them into Kelvin: We then move it to an air-conditioned room with a temperature of 15 ☌. Its initial volume is equal to 2 liters, and it lies on a beach where the temperature is 35 ☌.

Imagine that we have a ball pumped full of air. We can use Charles' law calculator to solve some thermodynamic problems.
