The concept involved here is specific heat capacity and the relation is q is equals to c multiplied by m multiplied by delta t.
00:10
So, q is the heat required, c is the specific heat capacity, m is the mass for given substance, delta t is the temperature change.
00:19
And furthermore we can write that this q will be equal to c multiplied by m multiplied by t2 minus t1.
00:31
So t2 is the final temperature, t1 is the initial temperature.
00:35
Now in such a case when a iron of different temperature, the metal of different temperature, that is put in water.
00:43
So, in such a case, we say that q gained, so heat gained, that will be equal to minus of heat lost.
00:55
Okay.
00:57
So now we can write that c1 multiplied by m1.
01:03
Multiplied by this will be here t2 minus t1 is equals to minus c2 multiplied by m2 multiplied by t2 minus t1 okay now putting the values the mass for iron that is 65 .0 gram multiplying we have this mass okay this is mass here the specific heat capacity that is 0 .4 4 .9 jule per gram per degree celsius multiplying the mass of iron we have that is 65 .0 gram...
