What is heat transfer? select one: o a. thermal energy in transit due to spatial temperature difference o b. thermal energy in transit due to spatial concentration difference o c. thermal energy in transit due to spatial mass difference o d. thermal energy in transit due to spatial pressure difference

a. Thermal energy in transit due to spatial temperature difference .

Explanation:

Heat transfer -

Heat transfer is the exchange of the thermal energy or heat in between any physical systems .

It is the flow of energy or any form of energy from one system to another .

Heat transfer is divided into various mechanism , one of which is the thermal .

The thermal energy is the transit due to the spacial temperature difference .

d.) circle motion requires a force to give it a centripetal acceleration.

the answer would be a
