1. A gas cylinder contains nitrogen gas at 10 atm pressure and a temperature of 20 C. The cylinder is left in the sun, and the temperature of the gas increases to 50 C. What is the pressure in the cylinder in KPa?

2.A given mass of air has a volume of 6.0 L at a pressure of 1.0 atm. What volume will it occupy at 190 mm Hg if the temperature does not change?

3.a. A gas with a volume of 4 L is allowed to expand to a volume of 12 L. What happens to the pressure in the container if the temperature remains constant?

b)The gas in a container has a pressure of 3 atm at 27 C (300 K). What will the pressure be if the temperature is lowered to -173 C (100 K)
