Three copper blocks of masses M 1 , M 2 and M 3 kg respectively are brought into thermal contact till they reach equilibrium. Before contact, they were at T 1 , T 2 , T 3 (T 1 > T 2 > T 3 ). Assuming there is no heat loss to the surroundings, the equilibrium temperature T is (s is specific heat of copper)
Text Solution
Verified by ExpertsThe correct answer is:
B
If the equilibrium temperature 
and 
but less than 
then as there is no heat loss to
the surroundings therefore heat lost loss to the surroundings therefore heat lost by 
and 
heat gained by
