Steel blocks A and B, which have equal masses, are at TA = 300 °C and TB = 400 °C. Block C, with mC = 2mA, is at TC = 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. TA = TB < TC. b. TA = TB = TC. c. TA = TB > TC. d. TA + TB = TC. e. TA ? TB = TC.
