How much thermal energy is required to take a 42.0 g block of ice at -12 degrees C and heat it to steam at 131 degress C?
Specific heat (ice) = 2.06 J/g degrees C
Specific heat (water) = 4.184 J/g degrees C
Specific heat (steam) = 1.996 J/g degrees C
Heat of fusion = 6.02 kJ/mol
Heat of vaporization = 40.7 kJ/mol
