Answer:
The molar volume increases
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.
