A gas storage tank has a volume of 15 L when the temperature is 115 C and the pressure is 114 kPa. What is the new volume of the tank if the temperature drops to -8.0 C and the pressure drops to 250.0 kPa? *

The new volume of the tank is 4.67 L

Explanation:

To calculate the volume when temperature and pressure 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 new volume of the tank is 4.67 L
