1. A balloon with volume 3200 mL of xenon gas is at a gauge pressure of 122 kPa and a temperature of 27°C. What is the volume when the balloon is heated to 65°C and the gauge pressure is decreased to 112 kPa?
2. A 7.85-L helium-filled balloon experiences a change in both pressure from normal atmospheric pressure to 60.5 kPa and temperature from 24.0°C to 6.00°C. What is the resulting volume?
