Temperature of given mass of a gas is changed from 150°C to 300°C during an isobaric process, volume of the gas will become:
Correct answer: D. Less than double
- A. Half
- B. Double
- C. Remain same
- D. Less than double
Explanation
During an isobaric process, the pressure of the gas remains constant. However, the volume of the gas is directly proportional to its temperature (according to Charles' law). When the temperature increases from 150°C to 300°C, the volume of the gas will increase. However, it will not double because the relationship between volume and temperature is not linear. As the temperature increases, the gas molecules gain more kinetic energy and move with higher speed, leading to increased collisions with the container walls. This causes an increase in pressure, which in turn affects the volume. As a result, the volume will increase but not double.

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.
