If the calorimeter is not well insulated, how will heat from the air in the laboratory affect the experimental value for the latent heat of vaporization?

Question 2

What is the time constant of the circuit shown in Figure OQ28.7? Each of the five resistors has resistance R, and each of the five capacitors has capacitance C. The internal resistance of the battery is negligible.

Answer to Question 1

A heat loss from the calorimeter cup will take place. Part of the heat energy from the
steam will be lost, and the value for the heat of vaporization calculated will be
lowered.
