Questions

- Calculate the amount of heat lost by the hot water after the ice was added.
Use the equation Q = mcDT 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
_{f}.

- How does your experimental value compare to the theoretical L
_{f}value for water? Explain any variation.

- Write a general equation to determine the total heat necessary to melt
ice into water.
