What is the:

Heat lost by Water (j)

Change in Ice Temp (Celsius)

Heat Gained by Ice after Melted (j)

Heat Used to Melt Ice (j)

Theoretical heat to Melt Ice (j)

% error

given the Initial volume of water = 70mL final volume of water = 100mL

given the initial temp of water = 24 degrees C final temp of water = 6 degrees C

Expert Solution

Here essentially the theoretical yield is same as the calculated value. This is because I calculated the mass of ice, which is a theoretical value. Usually in an experiment such values will be give and we can calculate part 3 and 4 easily.

3) Heat gained by ice after melting = mass of ice * 4.2 * 6

ie. m * c * ∆T

4) Heat used to melt ice = mass of ice * 336

Put the value of mass here and you will get the answer.

PS : If you have any doubt just comment below.
