2.) If the volume of a gas at -73 degrees celcius is doubled while pressure is held constant, what will be its final temperature in degrees celsius?

5.) A gas storage tank at a large industrial plant is designed to provide fuel under constant pressure. When the plant is shut down on friday afternoon, the volume of the tank is 21.5 m^3 at 75 deg. C. If the temp. drops to 30 degC by Monday morning, what volume will the fuel occupy at that time?

2) (V1/T1) = (V2/T2). Remember T must be in kelvin. The problem gives no initial volume except V. You can do either of two things.
a. Assume any number for V1; then V2 will be twice that number.
b. Just call the initial volume V1, then V2 will be 2V1.

5). Same procedure as 2) except you don't need to assume anything.
