Combined Gas Law

Combined Gas Law Name______Date______Pd. ______

P 1 V 1 = P 2 V 2 T1 T2

Temperature is measured in Kelvin for this law. Problem Work

1) A gas in a closed container with P1= flexible walls has a pressure of V1= 0 3 atm at -123 C and a volume T1= of 2 liters. If the temperature is 0 adjusted to 27 C, and the P2= pressure is changed to V2= standard pressure, what will the T2= new volume be? (6 pts)

2) Nitrogen gas contained in a P1= 50.0 L cylinder is bottled at 10 V1= atm of pressure and 200 K. The T1= cylinder is left in the sun. Its temperature reaches 27 P2= 0 Celsius. Assuming the cylinder V2= is made of metal and it doesn’t T2= change shape, what would the new pressure be? (6 pts)

3) 4.0 liters of a gas at –73.0 P1= 0 Celsius and 1.0 atm of V1= pressure expand to a volume of T1= 12.0 liters. The final pressure of the gas is measured to be 0.5 P2= atm. What is its temperature in V2= 0 C? (7 pts) T2=

4) A gas at standard pressure has P1= a volume of 6 L and a V1= 0 temperature of 27 C. If you T1= double the pressure and decrease the temperature to P2= 150 K, what will the new V2= volume be? (6 pts) T2=
