Unformatted text preview: one object continues to decrease, and that of the other continually increases. It is assumed that neither object undergoes a phase change nor a change in volume. Derive an expression which gives the minimum work required to decrease the temperature of the colder object to some final temperature, T fc , which is less than the initial temperature of both objects, T i . 3. If the temperature of the atmosphere is 5 ° C on a winter day and if 1 kg of water at 90 ° C is available, how much work can be obtained? Assume that the volume of the water is constant, and assume that the specific heat at constant volume is 18 cal/gmol-K and is independent of temperature. 4. Express the following in terms of C P , P, V, T, and derivatives of these variables: a) ( ∂ U / ∂ V ) T b) ( ∂ T / ∂ P ) H...
