Question

which of the following best describes heat?
a energy that flows from cold to hot objects
b energy stored in an object
c energy transferred due to a temperature difference
d energy that is always present
e energy that only exists in solids

Explanation:

Heat is defined as the energy transferred between two objects or systems due to a temperature difference. Heat naturally flows from a hot - object to a cold - object (not the other way around as in option a). Energy stored in an object is internal energy (not heat, option b is wrong). Energy that is always present is a very general and incorrect description for heat (option d). Heat is not exclusive to solids (option e is wrong).

Answer:

C. Energy transferred due to a temperature difference
