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.

Answer 1

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

Step-by-step explanation: I have taken this test before lol.

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

Answer 2

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

Step-by-step 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.
