If the volume of a gas is fixed then on increasing its temperature, its pressure_
Correct answer: C. Rises
- A. Gets negligible
- B. Gets constant
- C. Rises
- D. Falls
Explanation
Gay-Lussac's Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. With an increase in temperature, the pressure will go up.If the volume of a gas is fixed (constant volume), the relationship between pressure P, temperature T and the other gas properties is described by the ideal gas law:PV=nRTFrom this equation, we can derive that, for a fixed volume:P∝TThis means that pressure is directly proportional to temperature when volume is constant. Therefore, if the temperature is increased, the pressure also increase.

The more specific you are, the faster it gets fixed. A source beats an opinion.

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.
