1. A tire contains 1ft3 of air at a gauge pressure of 28lb/in2. How much additional air at atmosphere pressure must be pumped into the tire to raise the pressure to 36lb/in2 at the same temperature?
2. A gas having a volume of 100ft3 at 27°C is expanded to 120ft3 by being heated at constant pressure. To what temperature has it been heated to have this new volume?
3. A tire contains air at a gauge pressure of 28lb/in2 at 60°F. If the tire's volume does not change, what will be the gauge pressure be when its temperature is 100°F
4. A gas sample occupies a volume of 1m3 at a temperature of 27°C and a pressure of 1atm. Find its volume at 127°C and 0.5atm
