Heat flows from the hot to cold substance.

Option A

Explanation:

The medium or substance which has the higher temperature referred to as the hot substance transmits heat to the less temperature body or substance referred to as the cold substance. The temperature difference makes the heat flow from warmer substance to cooler substance.

The temperature thus flows through the gradient from high to low. This transmission takes place until both the substance in contact becomes equal in temperature.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
