    The heat of vaporization of water is 540 cal/g, and the heat of fusion is 80 cal/g. The heat capacity of liquid water is 1 cal g−1 °C−1, and the heat capacity of ice is 0.5 cal g−1 °C−1. 18 g of ice at -6°C is heated until it becomes liquid water at 40°C. How much heat was required for this to occur?

  • Calculate how many grams of ice at 0°C would be melted by 100 g of 100°C...

    Calculate how many grams of ice at 0°C would be melted by 100 g of 100°C steam. Hint: heat will be transferred from the steam to the ice in two processes: •the steam will condense into liquid, and •that liquid will transfer heat until it is at the freezing point of water. Note that for water: Lf = 80 cal/g (ice), and Lv = 540 cal/g (steam) (Use calories) C(water) =1 cal/g*C Answer in grams no decimal places.
