When a system is taken from state a to state b in the diagram below along the path acb, 90.0 J of heat go into the system and 60.0 J of work is done by the system. a) How much heat is transferred into the system along path adb if the work done by the system is 15.0 J? b) When the system is returned from b to a along the curved path, the absolute value of the work done by the system is 35.0 J. Does the system absorb or liberate heat? How much heat? c) If U = 0 J and Ua= 8.0 J, find the heat absorbed in the processes ad and db.

1.5 thermodynamics
The 1st law of thermodynamics is ΔU = Q –W. Use this statement of the 1st law to show (mathematically) its equivalent statement: “Total energy of the universe is constant”. Here, the universe can be defined as: system + surroundings (everything but the system –everything outside the system). (Hint: this can be shown by two ways-you may either treat system and surroundings as two systems next to each other, or you may treat system + surroundings (universe) as one system.)
