uestion 4: (a) An 88-litre gas cylinder is filled with propane gas at a pressure of 1.15 MPa and 18°C. The propane is used to fuel a gas burner. After some time, the pressure and temperature are 210 kPa and 23°C respectively. Determine the mass of propane used. The molar mass of propane is 44 g/mole. (b) A piston-cylinder device filled with air at 365 kPa and 12°C, has an initial volume of 1.3 litres. The air is expanded at constant pressure to a volume of 3.6 litres and 516°C. Determine the amount of heat and work involved in this process and state whether the heat and work are into, or out of the gas.
Once upon a time, an engineering is conducting an experiment wherein he uses 10 moles of a gas. He then places it in a constant volume vessel. At start the gas is at P = 0.5 bar and T =300 K and the container is also at T = 300 K. He decided to place it in a furnace, where its surroundings are at a constant T = 600 K. It was left overnight in the furnace until both the container and the gas inside it reach thermal equilibrium with the surroundings. He assumed an ideal gas for this experiment at the pressures attained throughout this process, and has a constant heat capacity of CV* = 2.5R. The container itself has a mass of 10 kg (not including the mass of the gas inside) and a heat capacity of CV = 1.5 J/g - K. ● Find the heat added to the gas. a. 62.4 kJ b. 46.4 kJ c. 90.4 kJ d. 87.4 kJ e. none of these Find the heat added to the container. a.588kJ b. 638 kJ c. 1457 kJ d. 3465 kJ Find the change in entropy of the gas a. 0.14 kJ/K b.0.3 kJ/K c. 0.78 kJ/K Find the change in entropy of…
Two insulated cylinders A and B with volumes VA = 1.2 m³ and VB = 6.4 m³ contain chlorine gas at different pressures and temperatures. The cylinders are insulated (no heat is lost to or gained from the outside) and connected by a valve. Initially, the valve is closed and the gas in the two cylinders has the following values: PA= 4.0 x 105 N/m2, TA= 250 K, PB = 2.5 x 105 N/m², Tg = 580 K. The valve is opened to allow the contents in the two cylinders to mix until the pressure equalizes. valve K TEACHER (a) Assuming there is no change in the temperatures of the containers themselves, determine the final temperature of the gas in the two cylinders. The atomic mass of chlorine gas is 35.4527 U. (b) Determine the final pressure. N/m²
