Final mass of cup and water (g)
Calculate the amount of heat lost by the hot water after the ice was added. Use the equation Q = mc
T where c is the specific heat capacity of water which is 4.184 J/g°C.
Calculate the amount of heat gained by the ice as it melted and then as the water increased to its final temperature.
Determine the amount of heat absorbed by the ice during the process. Use the answers to questions 1 and 2 to do this.
Calculate the experimental heat of fusion. Use the equation Q = mL
How does your experimental value compare to the theoretical L
value for water? Explain any variation.
Write a general equation to determine the total heat necessary to melt ice into water.
