At constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with the rise in temperature due to

Options

A. Increase in average molecular speed
B. Increase in the rate of collisions among the molecules
C. Increase in the molecular attraction
D. Decrease in the mean free path

Explanation

To solve the question regarding why the pressure of a gas increases with temperature at constant volume for a fixed number of moles, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Conditions**:
- We are dealing with a gas at constant volume and a fixed number of moles. This means that the volume of the container holding the gas does not change, and the amount of gas (in moles) remains the same.

2. **Relating Pressure, Volume, and Temperature**:
...
