Hello, here a rigid container contains 2 kilograms of co2 at the initial pressure of 100 kiosk and the initial temperature of 1 ,200 kelvin.
00:15
It's heated to the final temperature of 1 ,400 kelvin and we have to find the queue or heat.
00:24
We have to solve the final pressure, find the final pressure, and the heat transfer using the heat capacity of 0 .653 kilojoules per kilogram kelvin.
00:43
Let's do this.
00:44
So first let's start with a final pressure.
00:48
Here volume is constant because the container is rigid.
00:59
Therefore, final volume, sorry, initial volume over initial temperature.
01:07
Equals to final volume over final temperature, which is then final pressure equals to final temperature over initial temperature times initial volume.
01:22
That is 1 ,400 kelvin over 1 ,200 kelvin times 100 kilopascals.
01:30
So let's calculate it...
