Asample of methane gas, ch4(g), occupies a volume of 60.3 l at a pressure of 469 torr and a temperature of 29.3°c. what would be its temperature at a pressure of 243 torr and volume of 60.3 l?

The temperature when the volume and pressure has changed is -116.4°C

Explanation:

To calculate the temperature when pressure and volume has changed, we use the equation given by combined gas law. The equation follows:

where,

are the initial pressure, volume and temperature of the gas

are the final pressure, volume and temperature of the gas

We are given:

Putting values in above equation, we get:

Hence, the temperature when the volume and pressure has changed is -116.4°C
