Question

two solid blocks are heated to the temperatures shown. the blocks are placed so they touch. which diagram shows the direction heat will flow?

Explanation:

Step1: Recall heat - flow principle

Heat flows from high - temperature to low - temperature regions.

Step2: Compare given temperatures

One block is at 203°C and the other is at 197°C. So heat will flow from the 203°C block to the 197°C block.
