A cylinder is fitted with a frictionless piston and contains 0.250 moles of dry air, essentially composed of diatomic molecules (? = 7/5). The cylinder walls and piston are to a good approx- imation thermally insulating. Initially, air has a temperature of 353 K and occupies 74.0% of the cylinder’s volume. The piston is then gently pulled until the gas occupies the entire internal volume V of the cylinder. Calculate the final temperature of the 0.250 moles of air in the cylinder.

00:01 So, in this question we have to find heat that is exchanged that is exchanged from tank 1 to tank means from this tank 1 to cylinder.
00:11 As you can see in this figure there is a tank a having a volume of 100 liter and contains a saturated vapor of r 134 at 30 degree celsius.
00:23 Now, when the valve is cracked open r 134 flows into the cylinder b flows into the cylinder b this pistons require pressure of 200 kilo pascal in cylinder b to raise means to raise this piston to raise this piston we require 200 kilo pascal ok 200 kilo pascal pressure.
00:47 The pressure ends when the pressure in tank a has fallen to 200 means when this tank of the means in this tank a the gas is fallen up to 200 kilo pascal pressure automatically in this piston the 200 kilo pascal will be developed.
01:02 So, during this process the heat is exchanged with the surroundings such that r 134 a always remains at 30 degree celsius.
01:10 So, we have to find the heat transfer for the for this process.
01:15 So, for the means i can write the volume of a tank a is given what that is v a is equal to 100 liter.
01:23 So, convert into meter cube 0 .1 meter cube and say temperature at tank a is what 30 degree celsius as the temperature of this saturated gas is not changing.
01:34 So, i can write the heat developed in the heat developed in the tank a is what 400 15 .08 kilo joule per kg and the volume i can write that is the volume v 1 equal to v g 394 .48 kilo joule per kg.
02:00 If i want to convert in this into meter cube per kg...
