2. A sample of nitrogen gas has a pressure of 6.54 kPa at 537 K. If the
volume does not change, what will be the pressure at 179 K?

2.18 kPa will be the pressure at 179 K.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

where,

are the initial pressure and temperature of the gas.

are the final pressure and temperature of the gas.

We are given:

Putting values in above equation, we get:

2.18 kPa will be the pressure at 179 K.
