Hi, in this question we are given with dimension of room which is given in this way.
00:04
It is given that if there is temperature change from 27 degrees celsius to minus 3 degrees celsius, then this air would enter or lead the room.
00:16
The pressure value is given as constant and also we need to determine the volume of air which would move in or out of the room.
00:24
Here, first of all, we will find out the volume of room.
00:28
The volume of room will be equal to 16 into 12 into 12 which is length breath and height on multiplication we are getting the volume 2304 pete q now we will find out the volume of air that is compressed when there is decrease in temperature here we will use the charles law which says v1 by t1 is equal to v2 by t 2 by t 2 v1 is the volume of room and v2 will be the air which is compressed due to degrees in temperature.
01:06
We can say the v2 will be equal to v1 into t2 divided by t1.
01:14
We can substitute the values here.
01:16
In this manner, here we have converted the degree celsius value in kelvin by adding 273 to it.
01:23
Now we will eliminate the common unit kelvin from here.
01:26
On solving we are getting the v2 value...
