What is heat?
heat is the energy needed to change the temperature of 1 g of a substance by 1°c.
heat is the average kinetic energy of the particles of a substance.
heat is the total energy of a substance due to the movement of its particles.
heat is the energy that flows between two substances of different temperatures.

Heat is the energy that flows between two substances of different temperatures.

Explanation:

Heat is a type of energy in transition that is transferred by non-mechanical means between systems, which means that it is energy that is transferred (or that flows ) from one system to another.

This flow of energy occurs due to a temperature difference, and heat will flow from the system or substance with a higher temperature to the substance with a lower temperature, and if kept in contact they will eventually reach the thermal equilibrium.

So the correct answer is: Heat is the energy that flows between two substances of different temperatures.

The answer is D) Heat is the energy that flows between two substances of different temperatures.

Explanation: I have taken this test before lol.

Make sure to say thanks and leave a rate!! :)

whichever one it is, it's definitely not one that you included on the list you provided.

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

hope that                                         : )
