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.
