Some teenagers think that their parents are “full of hot air.” Your mom inhales 4 liters of air with a temperature of 20∘ Celsius. Since you think she is full of hot air, this temperature must increase while the air is in her lungs. If this air heats up to 37∘Celsius, what is the new volume of the gas?
