Please calculate the amount of energy it will take to change 20.0 grams of Water from -3°C all the way to vapor (100°C) at sea level. Please show all your work for credit.
heat of fusion of water = 334 J/g
heat of vaporization of water = 2257 J/g
specific heat of ice = 2.09 J/g·°C
specific heat of water = 4.18 J/g·°C
