9. Complete the following statement:

The term heat most accurately describes

A) the internal energy of an object.
B) a measure of how hot an object is.
C) the absolute temperature of an object.
D) the molecular motion inside of an object.
E) the flow of energy due to a temperature difference.

E) the flow of energy due to a temperature difference.

Explanation:

Heat can be described as the flow of energy due to a temperature difference.

Which is expressed mathematically as;

H = MCΔT

Where;

H is the quantity of heat in a body, measured in Joules

M is the mass of the body, measured in kg

C is the specific heat capacity of the body, J/kg.K

ΔT is change in temperature or temperature difference.

So, heat energy in any system flows from a hotter region to a colder region due to temperature difference.

E) the flow of energy due to a temperature difference.
