Question

Q8. Explain how charles' law helps us in finding out the absolute zero value.

Answer 1

Charles law: The temperature in kelvin and the volume will be directly proportional to each other if the pressure of a gas that is dry is held constant.

Absolute temperature: The scale where 0 acts as absolute zero while measuring the temperature is called as absolute temperature.  

Volume / Temperature = Constant

The Law can be used to experimentally find the value of absolute zero.
