URGENT PLEASE HELP!! 1. Why are the values for Molar Heats of Fusion always less than Molar Heat of Vaporization? In
other words, why is the energy required to boil matter always greater than the energy required to
melt it?
2. Calculate the energy required to boil 2.5g of water assuming the Molar Heat of Vaporization for
water is 40.7 KJ/mole. SHOW WORK FOR CREDIT BOX OUT YOU ANSWER
3. How much energy is required to bring 35g of ice at -10°C to a liquid at 15°C ?
Cp ice = 2.06 J/g°C Cp liquid = 4.18 J/gºC
