The label on an aerosol spray can contains a warning that the can should not be heated to over 130°F because of the danger of explosion due to the pressure increase as it is heated. Calculate the potential volume of the gas contained in a 495 mL aerosol can when it is heated from 25°C to 54°C (approximately 130°F), assuming a constant pressure.
