In this problem we will assume that let q1 be the heat to bring the ice at 0 degree celsius.
00:12
So therefore q1 is equal to what? q is equal to ms of ice multiplied with delta t.
00:21
So we will just put the values.
00:23
Therefore q1 is equal to what? q1 is equal to ms of ice multiplied with 0 minus of minus 20.
00:36
So this is equal to what? this is equal to 4180 joule.
00:40
So this is the value of q1.
00:42
We mark this as equation number 1.
00:44
So now we will find the value of q2.
00:46
So what is q2? q2 is the latent heat which is required to what? which will convert ice at 0 degree to water at 0 degree.
01:01
So therefore we can write that therefore q2 is equal to what? q2 is equal to m multiplied with l.
01:09
So that is equal to what? 100 multiplied with 334 and the unit is what? it is in joules.
01:17
So therefore we get that q2 is equal to what? q2 is equal to 100 multiplied with 334 that is 33400 joules.
01:30
We mark this as equation number 2.
01:33
So now we will calculate q3.
01:36
So what is q3? q3 is the heat for raising water to what? to 100 degree celsius.
01:43
So therefore q3 is equal to what? q3 is equal to m multiplied with s of water multiplied with delta t.
01:55
So we will just put the values that is 100 multiplied with 4 decimal 184 multiplied with what? multiplied with 100 minus 0.
02:05
So therefore we get the value of q3 is equal to what? this is equal to 41840 and the unit is joules.
02:14
We mark this as equation number 3.
02:16
And finally we will calculate the value of q4...
