Hi friends given ideal diatomic gas undergoing adiabatic expansion.
00:29
Initial volume is 0 .750 meter cube.
00:36
Final volume is 1 .50 meter cube.
00:42
Initial pressure is 1 .510 to the power 5 pascal.
00:49
Final pressure is sorry.
00:58
In the first part we have to find.
00:59
The number of moles.
01:01
You can use ideal gas equation, pi, vi is equal to n rti.
01:09
Substitute the value.
01:10
Pressure is given 1 .510 to the power 5.
01:15
Volume is given 0 .75 and we are finding gas constant 8 .314 into 325 given and initial temperature is 325 kelvin.
01:36
So number of moles you will get 41 .64.
01:54
Second part.
01:56
Final pressure using the equation p final, b final, is called to p initial, v initial to the power gamma.
02:11
So you can write p -i -b -i -upon b -f -f -to -the -power gamma.
02:19
Substitute the value.
02:21
Initial pressure is 1 .1...
