Question

What is Charles's law?

Answer 1

`"Charles' Law"` states that at constant pressure, and constant amount of gas, `VpropT`.

Explanation:

The temperature is specified to be on the absolute scale, i.e. `"Kelvin scale"`.

Thus `VpropT`, `V=kT`

Solving for `k`, `V_1/T_1=V_2/T_2`.

This is the defining relationship for the steam age, where steam was used to drive pistons and locomotives etc. on the basis of this law.
