Question

Based on Gay-Lussac's law, which of the following statements is true for an ideal gas at constant volume and mole amount?

A. The number of collisions is independent of pressure.

B. The number of collisions decreases with increase in pressure.

C. Pressure is directly proportional to the absolute temperature.

D. Pressure is inversely proportional to the absolute temperature.

Answer 1

Option C. Pressure is directly proportional to the absolute temperature.

Explanation:

The ideal gas equation is given as:

PV = nRT

P = nRT/ V

Since n and V are constant, it means that P will be directly proportional to the absolute temperature
