Consider the following statements and choose the correct answer. a) if heat is added to a system, its temperature must always increase. b) if positive work is done by a system in thermodynamics process, its volume must increase.

Heat of 30 kcal is supplied to a system and 4200 J of external work is done on the system so that its volume decreases at constant pressure. What is the change in its internal energy. (J=4200 J/kcal)

Express the change in internal energy of a system when 1) No heat is absorbed by the system from the surroundings, but work (w) is done on the system. What type of wall does the system have ? ii) No work is done on the system, but a amount of heat is taken out from the system and given to the surroundings. What type of wall does the system have? iii) w amount of work is done by the system and q amount of heat is supplied to the system. What type of system would it be?
