Question

Three copper blocks of masses M1, M2 and M3 kg respectively are brought into thermal contact till they reach equilibrium. Before contact, they were at T1, T2, T3 (T1 > T2 > T3 ). Assuming there is no heat loss to the surroundings, the equilibrium temperature T is (s is specific heat of copper)

Options :

  1. T = (T1+T2+T3)/3

  2. T = (M1T1+M2T2+M3T3)/(M1+M2+M3)

  3. T = (M1T1+M2T2+M3T3)/3(M1+M2+M3)

  4. T = s(M1T1+M2T2+M3T3)/(M1+M2+M3)

Show Answer

Answer :

T = (M1T1+M2T2+M3T3)/(M1+M2+M3)
