Question

Two copper blocks A and B have equal mass and temperatures of 300^oC and 400^oC, respectively. A third block (C), with a mass twice that of A, has a temperature of 350^oC. Blocks A and B are placed in thermal contact and allowed to reach thermal equilibrium. Which of the following statements is correct?

T_A = T_B < T_C

T_A = T_B > T_C

T_A - T_B = T_C

T_A + T_B = T_C

T_A = T_B = T_C

Expert Solution

Step 1

$Let mass of block A = m Let mass of block B = m Let mass of block C = 2 m {Initial temperature of A = 300}^{o} C {Initial temperature of B = 400}^{o} C {Initial temperature of C = 350}^{o} C$
