Steel Blocks a and B, Which Have Equal Masses, Are

question 21

Multiple Choice

Steel blocks A and B, which have equal masses, are at T_A = 300 °C and T_B = 400 °C. Block C, with m_C = 2m_A, is at T_C = 350 °C. Blocks A and B are placed in contact, isolated, and allowed to come into equilibrium. Then they are placed in contact with block C. At that instant,

• A) T_A = T_B < T_C.
• B) T_A = T_B = T_C.
• C) T_A = T_B > T_C.
• D) T_A + T_B = T_C.
• E) T_A − T_B = T_C.
