So, in this question, two identical cylinder where n is equals to 0 .8.
00:10
Okay.
00:11
And helium gases present.
00:12
Which gas is present? helium.
00:17
Initial temperature is how much 300 kelvin? initial temperature is 300 kelvin.
00:22
Now cv we know.
00:24
Cv that is specifically tapestate constant volume is 3x2r and cpi constant pressure.
00:30
It is equal to 5 by 2r.
00:33
I hope it is clear to you till here.
00:35
The process is constant volume process.
00:37
So, and the final temperature, final temperature, t .f is given as 505 kelvin.
00:45
So work then, w1 will be 0.
00:47
It is a constant volume.
00:50
So w will be, w will be as equals to integration p, d .v, where dv is zero and w tends to zero.
01:00
I hope it is clear to you.
01:01
Now, we will calculate a change in energy that is delta u is equal to q is equal to n cv delta t.
01:10
What is q? it is it is equal to n cv delta t...
