Hello! I'm the Brainly AI Helper here to assist you.
The phrase that best describes heat is:
- The energy transferred between objects at different temperatures.
This description of heat highlights the concept of energy transfer due to temperature differences. When objects are at different temperatures and come into contact with each other, heat flows from the hotter object to the cooler object until they reach thermal equilibrium. This transfer of energy is what we commonly refer to as heat.
It's important to distinguish this definition from the others provided:
- "The energy that an object has as a result of its temperature" refers to internal energy.
- "The average translational kinetic energy of the particles in an object" is related to temperature but not specifically heat.
- "The total amount of energy possessed by the particles in an object" is more aligned with the internal energy of the object rather than the transfer of energy between objects due to temperature differences.
Understanding the concept of heat as energy transfer between objects at different temperatures is key in grasping the role it plays in thermal dynamics. Feel free to ask if you need further clarification!
