Hello, here we have to solve the problem.
00:04
The device initially contains pressure of 150 khalpascals at the initial temperature of 27 degrees c.
00:16
That is 300 kelvin.
00:18
At this state, the initial volume is 400 liters and the mass of the piston is such that it starts moving under p, under the p, under the pressure of 350 kilopascals.
00:45
The air is heated until the volume is doubled.
00:49
It means that the final is to be initial.
00:52
First, we have to determine final temperature.
00:57
Let's look at this process.
00:59
The overall process can be split into two parts.
01:03
First, that is isochoric.
01:09
It means that volume is constant heating.
01:17
And then, that is is a isochic.
01:18
The barric means that pressure is constant heating or expansion so let's realize the conservation of let's write down the ideal gays law for the initial condition so that is p initial v initial is n number of most times are t initial then for station two and here station 2 is between process 1 and so that means that p2 the initial is n rc2 and actually here p2 is p2 is p2 is p that is the pressure needed to move the cylinder to move the piston and now let's write down for the final state and the final state p times three final equals to nrt final let's analyze equation one and equation three let's divide equation three by equation one so p times three final over p initial v initial equals to t final over t initial.
03:02
Therefore, t final is t initial times p v final over p initial v initial...
