Two solid blocks are heated to the temperatures shown. The blocks are placed so they touch.

Question

Which diagram shows the direction heat will flow?

A. 160 deg * C <--HEAT 141 deg * C

B. 160 deg * C HEAT--> 141 deg * C

C. 160 deg * C NO HEAT FLOW 141 deg * C

Block A

Block B

Block C

Answer 1

The correct answer is B. 160 deg * C HEAT--> 141 deg * C. Heat always flows from a higher temperature to a lower temperature, therefore, heat will flow from the block with a temperature of 160 deg * C to the block with a temperature of 141 deg * C.
