In order for heat to flow there must be... * A. identical tempatures

B. a difference in tempatures

C. a difference in altitude

D. an electrical current present

B. a difference in temperatures.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles.

Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

In order for heat to flow there must be a difference in temperatures.

This ultimately implies that, the driving force responsible for heat to flow is a difference in temperature between the points from which heat originates and where heat is received.

Additionally, the higher the temperature difference, the greater would be the heat flow; which is usually from a high temperature level to a low temperature level.
