Pressure , Volume & Temperature

A 0.905 mol sample of Ar gas is confined in a 22.6 liter container at 31.6 °C.

If the volume of the gas sample is increased to 45.2 L holding the temperature constant, the average force per molecule-wall collision will-

1) increase.

2) not enough information to answer the question.

3) remain the same.

4) decrease.

Expert Solution

A 0.905 mol sample of Ar gas Volume-22.6 liter container at 31.6 °C.

increase in volume- 45.2 L holding the temperature constant.

Given that the Volume is increased at constant temperature.

As we know at constant temperature the average speed of particle remains same .

So if the speed remains same then the force per molecule-wall collison will also remain same.

Hence , The answer is remains the same.

There will be no effect on Force per molecule-wall collesion .
