Task 1: A. Describe the operation of the following thermodynamic systems and their properties: (i) System (ii) Surroundings (iii) Open System (iv) Close System (v) Isolated System B. A large fraction of the thermal energy generated in the engine of a car is rejected to the air by the radiator through the circulating water. Should the radiator be analysed as a closed system or as an open system? Explain. C. The molar specific volume of a system v is defined as the ratio of the volume of the system to the number of moles of substance contained in the system. Is this an extensive or intensive property? D. What is specific gravity? How is it related to density?
