Answer:
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.
A polar molecules have charges that are free to move around
