How will using wet ice (some water at 0C is added along with the ice) affect the experimental value for the latent heat of fusion of ice? Explain.

Question 2

The accepted value for the heat of fusion of ice is 80 cal/g. This is the amount of energy that must be transferred into one gram of ice at its melting temperature (0C) in order to change it into liquid water. Also, 80 cal/g is the amount of energy that must be removed from one gram of water at 0C in order to change liquid water to ice. Calculate the percent error for your experimental value of the heat of fusion of ice using this value as the standard. Show your work.

Answer to Question 1

The calculated value for the heat of fusion of ice will be lower, because the mass of
melted ice water in the experiment will be greater.

Answer to Question 2

The percent error should be 5 percent or less. Refer to Appendix III for an equation to
calculate percent error.
