In problem 11, what was the initial volume? so this question is taken from the chapter gases.
00:06
And in this question, we apply the concept of combined gas law.
00:18
So it is a relationship between the two different pressure, volume and temperature, which is given by p1 v1 divide by t1 is equal to p2 v2 divide by t2.
00:30
So in this case here, p1 represents the initial pressure of the gas.
00:40
V1 represents the initial volume and t1 represents the initial temperature and v2 represents the final pressure then v2 represents the final volume and t2 represents the final temperature.
01:34
Okay so in this question we find out the initial volume so that means we find out the value of v1 and the value of p1 which is given in the equation that it is 1 .0 to atm.
02:03
So this is the initial pressure 1 .0 to 8m and temperature t1 which is also given.
02:14
This is around 22 degrees celsius.
02:18
So we can convert into the kelvin.
02:21
So, 22 degrees celsius is equal to 22 plus 273, so which means 295 kelvin...
