Hello students here the question is in regarding to we have to choose the lowest temperature from the given different temperatures and the temperature here given in different units now we have to consider which will be the lowest temperature and in that case the first one is given as minus 100 degrees centigrade i'm taking this as t1 in order to compare the lowest temperature i am converting every temperature into kelvin so t1 is equal to minus hundred degree centigrade.
00:32
We should require the relationship between the degree centigrade and kelvin.
00:37
That is kelvin is equal to degrees and 273.
00:42
This is the relationship between this.
00:45
Now we have to convert the t1 into kelvin.
00:48
That is t1 is equal minus 100 plus 273 kelvin from which we are getting t1 as 173 kelvin.
01:02
Now let us go for the second one in which the temperature is given in the kelvin itself.
01:13
Let us consider that.
01:14
D is given 273 kelvin itself.
01:18
So this t2 is equal to 273 kelvin.
01:22
So there is no need for to convert into another unit.
01:28
Let us consider the third one.
01:30
Here, minus 100 foreign heat is given here.
01:36
Now we need to convert the foreign heat first into degrees centigrade and then to kelvin.
01:42
Let us find out that.
01:44
First of all, we should require a relationship between the foreign heat and degrees centigrade...
