Thermodynamics- Gas mixture compression
An ideal gas mixture at P1 and T1 is compressed in a piston
cylinder assembly first isothermally to P2 and then isentropically
(reversible and adiabatic) to T3. Assuming variable specific heats
(use ideal gas tables) determine the following given the properties
listed below.
--Given Values--
m_O2 (kg) = 0.38
m_N2 (kg) = 0.34
T1 (K) = 650
P1 (bar) = 1.32
P2 (bar) = 2.52
T3 (K) = 738
1. Determine the pressure (bar) at state 3
when solving for K, where do they get 1.33 and 1.366 from?

Thermodynamics Ideal Gas
Air confined to one side of a rigid container divided by a partition, as shown in Fig.2.The outer side is initially evacuated.The air is initially at p1=5 bar,T1=500 K, and V1= 0.2m3. When the partition is removed, the air expands to fill the entire chamber. Measurements show that V2=2V1and p2=p1/4.Assuming the air behaves as an ideal gas, determine (a) the final temperature, in K, and (b)the heat transfer, kJ.

2 moles of compressed air (diatomic gas) in a cylinder under the initial condition T1=573K p1=500kPa. Found v1=0.019m^3 but can not remember then how to find V2. I think that it has something to do with T1=T2 condition then P2 can be found.... but stuck on how to proceed so with FULL written explanations with working would be much appreciated! All question info on practice exam below - note ISOTHERMAL EXPANSION. for part ii which after an explanation first. Two...
