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.

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.
