Question
An object is in equilibrium at 400 K.Calculate its change in Helmholtz free energy when heat is transferred from the object to lower its temperature
An object is in equilibrium at 400 K. Calculate its change in Helmholtz free energy when heat is transferred from the object to lower its temperature to 284 K while the environment remains at 400 K.
Assume that the heat capacity of the object is C = 0.7 kJ K-1.
State your answer in kilojoules as a number in normal form accurate to 2 decimal places. Do not include units in your answer.
