1. A Gas at 45 degrees Celsius and 3.2 atm has its pressure increase to 5atm. What will its final temperature end up being? 2. A gas exerts 9 atm at 50 degrees Celcius. How much pressure will exert at 100 degrees Celcius? 3. A gas has its pressure decrease from 380 torr to 160 torr at 112.5K. What was the initial temperature of the gas? 4. The pressure of a nitrogen gas inside a rigid tank is 1.5 atm at 30 degrees Celcius. What will be the resulting pressure if the tank is cooled to 0 Degrees celcius?
