A hot air balloon is filled with 1.41 × 106 L of an ideal gas on a cool morning (11 °C). The air is heated to 111 °C. What is the volume of the air in the balloon after it is heated? Assume that none of the gas escapes from the balloon.
If the pressure is constant you could use the fact that volume is proportional to temperature, so:
V2 = V1*T2/T1
