An ideal gas with Cp = 2.5R at 298 K and 5.00 bar is adiabatically throttled to 1.00 bar. If the flow rate of gas is 1.71 mol/s, and the surroundings are at a temperature of 3°C, what is the rate of lost work, in kW? Please give your answer to 3 SF, and be very careful with units.

An ideal gas with ?=1.4 occupies 3.0L at 300 K and 100kPapressure and is compressed adiabatically until its volume is 2.0 L. It's then cooled at constant pressure until it reaches 300 K, then allowed to expand isothermally back to state A. Part A Find the net work done on the gas. Express your answer using two significant figures. Part B Find the minimum volume reached. Express your answer using two significant figures.

An ideal gas described by Ti = 300 K, Pi = 2.00 bar, and Vi = 15.0 L is heated at constant volume until P2 = 20.0 bar. It then undergoes a reversible isothermal expansion until P3 = 2.00 bar. It is then restored to its original state by the extraction of heat at constant pressure. Depict this closed-cycle process in a P-V diagram.

5 moles of ideal gas is initially at 300 K and 5 bar. It is compressed to 10 bar at 300 K. This change is carried out by two different reversible processes: A: heating at constant volume followed by cooling at constant pressure B: cooling at constant pressure followed by heating at constant volume Depict these processes on a PT graph.

b) Ethane gas at 1 bar and 25 oC is compressed adiabatically to 55 bar in a steady-state flow process for which W = 10 J mol-1. Assume ethane is ideal gas at its initial state and the residual enthalpy of the gas at its final state is - 3270 J/mol, and its heat capacity is constant (CP = 4.5 R), the temperature of ethane at the final state, i.e., after compression, is i. 403.3 oC; ii. 403.3 K; iii....
