Question

Anytime a temperature difference occurs, you can expect

• A. energy movement flowing slowly from cold to warmer regions
• B. energy movement from high temperature regions
• C. no energy movement unless it is warm enough, at least above the freezing temperature
• D. cold to move to where it is warmer

Answer 1

The correct option is B

energy movement from high temperature regions

Heat tends to move from a region with higher temperature to a region with a lower temperature just as a ball tends to roll downhill. You must give a ball more energy to move it uphill and more energy is required to pump heat from a cooler region to a warmer one.
