Question 1- Name one main difference between closed systems (control mass) and open systems (control volume)? Question 2- Circle the propertics: Temperature mass flow rate mass convective heat transfer Question 3 - What is an isothermal process? Question 4 - Choose the list consisting only of intensive properties: a) Volume, temperature, pressure b) Specific volume, mass, volume c) Pressure, temperature, specific volume d) Mass, temperature, pressure Question 5 - A system is said to be at if none of its properties change with time. Question 6 - A special type of closed system that does not interact in any way with its surroundings is an Problem 1- A gas contained within a piston-cylinder assembly undergoes the following processes in series: Process 1-2: constant pressure expansion at 100kPa from V1=50m3 to V2100m3 Process 2-3: constant volume to 150kPa Process 3-4: constant pressure expansion to 150m3 Sketch the processes in series on a P-V diagram. Problem 2-A pressure gage connected to a tank reads 55kPa at a location where the atmospheric pressure is 101:325kPa. Calculate the absolute pressure in the tank. Problems 3- The temperature of ambient air in a certain location is measured to be 40C. Express this temperature in Farenheit ( F), Kelvin ( K), and Rankine (R). Problem 4- A vacuum gage connected to a chamber reads 35kPa at a location where the atmospheric pressure is 92kPa. Determine the absolute pressure in the chamber
