Hi, so in this question, we have object a has a greater mass on object b, and they are made from the same material, and the two have different temperatures.
00:11
So i want to find out what happens when they are brought into thermal contact, how the temperatures change.
00:16
So the formal we're going to use is h is equal to mc, delta t.
00:24
And so h is the heat exchange, transferred, m is the mass, c is the specific heat capacity, and delta t is the change in temperature.
00:34
So you make delta t the subject you have delta t is equal to h over mc so for these two objects and contact we know that they are the same material and that means that they have the same specific heat capacity so c is the same for both and but the masses are different and you have h h is the heat transferred and so it's going to be the same for both because they're in time of contact so the heat transfer into one is going to be the heat that leaves the other and vice versa so, we know that a has greater mass.
01:12
And since this mass is divided here, the greater mass, the smaller the change in temperature.
01:21
And so since object a has greater mass, object a will have the smaller change in temperature...
