A piston-cylinder contains nitrogen initially at 100 kPa, 20°C, and a volume of 0.283 m (State 1). The nitrogen undergoes two processes. First, the nitrogen is compressed to 7000 kPa (State 2) in an isothermal process. Finally, the nitrogen is expanded to 100 kPa (State 3) in a reversible adiabatic process. You may assume that nitrogen is an ideal gas with constant (average) specific heats: Cp = 1.039 kJ/kgK, c, = 0.742 kJ/kgK, and R = 0.297 kJ/kgK. %3D %3D

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

2. What is the final temperature of the nitrogen in °C?

A piston-cylinder contains nitrogen initially at 100 kPa, 20°C, and a volume of
0.283 m³ (State 1). The nitrogen undergoes two processes. First, the nitrogen
is compressed to 7000 kPa (State 2) in an isothermal process. Finally, the
nitrogen is expanded to 100 kPa (State 3) in a reversible adiabatic process. You
may assume that nitrogen is an ideal gas with constant (average) specific heats:
Cp = 1.039 kJ/kgK, c, = 0.742 kJ/kgK, and R= 0.297 kJ/kgK.

R-134a is a refrigerant, which is used inside of refrigerators and air conditioners. You can buy canisters of this as a compressed liquid, which can be used to recharge a leaky air conditioner. The canister initially contains 0.539 kg of R-134a at room temperature (25 °C). For simplicity, let's assume that the R-134a is initially saturated liquid. You use this canister to recharge an air conditioner, until the canister has half of its original mass remaining. The canister is upright with the exit on the top of the canister, so the exit flow is saturated vapor. In order to maintain the temperature at 25 °C, how much heat must be supplied to the canister? Note that this is why compressed liquid/gas canisters feel cold when you use them – they require heat - input to maintain constant T.

A well-insulated 4 × 4 × 5 m³ room, initially at 10 °C, is heated by the radiator of a steam heating system. The radiator has a fixed volume of 150 L and is initially filled with superheated water vapor at 200 kPa and 200 °C. After 30 minutes, the pressure of the steam is observed to drop to 100 kPa as a result of heat transfer to the room. Assume constant specific heats for air.
