1) One radiator has a volume of 0.09mt³. It contains saturated vapor at a temperature of 100°C. The inlet and outlet valves of the radiator are closed and as a result of the heat transfer the temperature decreases 80°C.
Find:
a) The total mass of vapor in the radiator
b) The volume and mass of liquid in the final state
c) The volume and mass of vapor in the final state
d) The pressure in the final state.
2) One system has an initial volume of 1mt³ and expands to a final volume of 2mt³. The initial pressure is 100 Kpa. Find the work made if the system maintains a temperature of 20°C and the pressure in the final state of the system is:
a) Constant (P1=P2).
b) Inverse to the volume (P=C/V).
c) Behaves like an ideal gas.
