Hello, in the given question, the initial temperature, volume and pressure of helium gas is given and after cooling, the final temperature and pressure is also given.
00:11
We have to find the final volume.
00:13
So first of all, we will convert the temperature into kelvin.
00:16
So t1 will be equal to 23 plus 273 and this is equal to 296 kelvin.
00:25
Similarly, we will convert the final temperature and this is equal to 15 plus 273.
00:31
And this is equal to 288 kelvin.
00:35
Now we will use the ideal gas equation to solve this and according to that, p1 v1 divided by t1 is equal to p2 v2 divided by t2.
00:46
We will rearrange this and final volume v2 will be p1 v1 t2 divided by t1p2...
