Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant. For example, the residual pressure in a can is 1.31 atm when it is sitting on a shelf at 23 ^\circ \rm C. If the can is placed on top of the furnace where the temperature reaches the boiling point of water, what is the pressure inside the can?
