A sample of gas at 80°C is cooled by 30 degrees until its final volume is 1.75 L. If the pressure remains constant, what was the initial volume of the gas.

Answer 1

(V1/T1) = (V2/T2)
Remember T must be in kelvin.

Answer 2

Suppose that 2.3 L of gas at 35°C and 1.0 atm is expanded to 4.5 L at 42°C. What will the final pressure of the gas be?

Answer 3

(P1V1/T1)=(P2V2/T2)
