Faculty of Engineering Thermodynamics 1 Course code: MPE 101 Sheet 1: BASIC CONCEPTS OF THERMODYNAMICS 1. What are the types of thermodynamic system? 2. What is the difference between intensive and extensive properties? 3. A can of soft drink at room temperature is put into the refrigerator so that it will cool. Would you model the can of soft drink as a closed system or as an open system? Explain. 4. 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 analyzed as a closed system or as an open system? Explain. 5. Define state, process and cycle. 6. Define the zeroth law of thermodynamics. 7. Determine the types of thermodynamic equilibrium, realize each one. 8. A 3-kg plastic tank that has a volume of 0.2 m3 is filled with liquid water. Assuming the density of water is 1000 kg/m3, determine the weight of the combined system. 9. Consider a system whose temperature is 37°C. Express this temperature in K and °F. 10. The temperature of a system rises by 70°C during a heating process. Express this rise in temperature in kelvins. 11. What is the difference between gage pressure and absolute pressure? 12. A vacuum gage connected to a chamber reads 35 kPa at a location where the atmospheric pressure is 92 kPa. Determine the absolute pressure in the chamber.
