When an ideal gas of constant mass is heated in a container of fixed volume. What is the reason for the increase in pressure of the gas?
Correct answer: C. Average force per impact at the container wall increases
- A. Number of molecules per unit volume increases
- B. Molecules occupy a greater volume of the container
- C. Average force per impact at the container wall increases
- D. Molecules collide with each other with greater force
Explanation
In ideal gas the pressure is due to the collision of gas atoms with walls of the container. When heat is supplied molecules gain K.E and hit the walls with greater force.as force with which molecule hit increases ,pressure increases.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
