Ideal Gas Law y Aerosol cans carry clear warnings against incineration because of the high pressures that can develop upon heating. Suppose that a can contains a residual amount of gas at a pressure of 755 torr and a temperature of 25 o C. What would the pressure be if the can were heated to 1155 o C?
