When gasoline evaporates from a fuel gas can, the change in entropy is positive and the change in enthalpy is also positive. This means that the vapor pressure of the gasoline increases and the temperature of the fuel gas can decreases. The increased vapor pressure causes the gasoline to vaporize more quickly, while the decreased temperature causes the vapor to condense more slowly.
