You are to design a procedure to determine experimentally the specific heat of an unknown liquid. You may not damage or destroy any equipment you use, and your method must be feasible and practical.

	(a) List the equipment you would need. Include a labeled diagram.

	(b) Describe the measurements you would make. Assign each measurement a symbol (such as time = t).

	(c) Show explicitly using equations how the measured quantities would be used to determine the specific heat of the unknown liquid.

	(d) Indicate one possible source of experimental error and discuss how it would affect your value for the specific heat. Justify your answer.
