Explanation:
- We can observe no change in the temperature when the gas is ideal. Moreover, the law of Charles’ relates the temperature with volume, but not temperature with pressure.
- So, we cannot explain the reason behind the phenomenon using the law of Charles.
- It is to be understood that Charles’s law is an experimental gas law, which explains how the expansion of gas takes place when heated.
- According to the Charles’s law’s modern statement: when the dry gas’ sample’s pressure is held constant, the volume and Kelvin temperature will always be in direct proportion.
