Answer 2

A gas behaves more closely as an ideal gas at low pressure and high temperature.

Explanation:

• It is to be noted that the gas concentration will be low at the low pressure.
• So, the assumption of the kinetic energy that the molecules size is negligible when compared to the container’s volume applies.
• Molecules move faster at high temperature.
• Thus, they elastically collide and there will be a minimization of the interaction of forces between the molecules.
• This is the idea condition required. So, the correct answer is (b), which is low pressure and high temperature.
