Question

a calorimeter of mass m having an equal mass of water in it. the temperature of the water and calorimeter is t2. a block of ice of mass m and temperature t3<0 is dropped into calorimeter. let c1 c2 and c3 be the specific heats of the respective then

Answer 1

Hope this helps.
If we place a hot body in contact with a cold one, the former becomes colder and thelatter becomes warmer. Therefore, we can say, a temperature change has occurred between the two bodies and finally a thermal equilibrium is established. We say that acertain quantity of heat has passed from the hot body to the cold one. There is a
heat flow
or
heat transfer
between the two bodies. Count Rumford (1753 – 1814) and Sir JamesPrescott Joule (1818 – 1889) established that this heat flow is an
energy transfer.
