For this question, we need to know the relationship between the pressure of a gas and its temperature.
00:06
The initial pressure divided by the initial temperature will equal the final pressure divided by the final temperature.
00:12
Rearranging this, the final temperature will be equal to the final pressure multiplied by the initial temperature divided by the initial pressure.
00:21
The final pressure was 4 .11 atmospheres.
00:29
The initial temperature was 27 degrees.
00:33
But when using this equation, temperature must always be in kelvin, so we'll add 273 to that to get it into kelvin.
00:42
We'll then divide by the initial pressure of 1 .15 atmospheres.
00:50
And we get, so long as the volume, the number of moles stay constant, 1 ,072 kelvin.
00:59
If we subtract 273 from that, that will convert it into a celsius temperature.
01:07
Which gives us 799 degrees celsius...
