Answer: Option (C) is the correct answer.
Explanation:
When we provide heat to a substance then its molecules start to vibrate more rapidly. As a result, molecules gain kinetic energy and collide more rapidly.
Hence, this energy is given off in the form of heat.
So, when two objects with different temperatures are placed adjacently in contact with each other then heat will transfer from hotter object to colder object.
Thus, we can conclude that the phrase energy transferred between objects at different temperatures best describes heat.
