Question

What happens to the molar volume when the temperature increases​

Answer 1

Volume is inversely proportional to pressure, if the number of particles and the temperature are constant. There are two ways for the pressure to remain the same as the volume increases. ... This happens when the temperature is increased.

Answer 2

The molar volume increases

Step-by-step explanation:

By the Law of Charles-Gay Lussac (for ideal gases) which can be applied to a real gas, we can say that when a fixed mass of gas is heated, at constant pressure, its volume increases.

Law of Charles-Gay Lussac says:

V(Volume)= K(proporcionality constant)* T(Temperature)

or

Initial Volume/Inicial Temperature=Final Volume/Final Temperature

You can calculate the Final Volume.

This is because the temperature increases the energy of the molecules and also their speed, therefore the volume increases.

For example, if two moles of a gas have a constant pressure, as their temperature increases, their volume will also do so.
