For this problem, we have an ideal diatomic gas that expands adjutically from volume of 0 .59 meter cube to volume of 1 .66 meter cube.
00:25
The initial pressure is 1 .4 times 10 place to 5 pascal.
00:33
And the initial temperature is 365 kerd.
00:39
So question a, asked us to determine the number of modes.
00:45
So this is an ideal gas, we can use t, an ideal gas law, to determine the number of moles, which is six.
00:51
By isolating the end to the life -side location, then we have this.
00:58
Since we are given the initial pressure, volume temperature, we can use that here.
01:07
In solving, 1 .4 times 1085 pascal, not the guide by 0 .59 meter tube, over his, the gas consent is 8 .31 gyros per more kelvin.
01:26
The initial temperature 25 kelvin.
01:29
In solving, you can find that the number of moles is approximately equal to 208 moles.

Now, queshing b asked for the final pressure...
