5) Show that Q total in cal is needed to change 50 g of 0 ̊C ice to steam at 100 ̊C.

  1. (a) Show that Q in cal, Quantity of heat is needed to increase the temperature of 50 g water from 0 ̊C to 100 ̊C. The specific heat capacity for water is 1 cal/g•̊C.

  2. (b) Show that Q in cal, Heat of fusion is needed to melt 50 g of 0 ̊C ice. The heat of fusion Lffor water is 80 cal/g.

  3. (c) Show that Q in cal, Heat of vaporization is needed to turn 50 g of 100 ̊C boiling water into steam. The heat of vaporization for water Lv is 540 cal/g.

  4. (d) Sum the heat of fusion, quantity of heat, and heat of vaporization in order to calculate the Q total in cal is needed.

    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.
