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 :
T = (T1+T2+T3)/3
T = (M1T1+M2T2+M3T3)/(M1+M2+M3)
T = (M1T1+M2T2+M3T3)/3(M1+M2+M3)
T = s(M1T1+M2T2+M3T3)/(M1+M2+M3)
Answer :
T = (M1T1+M2T2+M3T3)/(M1+M2+M3)
