Answer:
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 .
The mass of electrons, protons, and neutrons:
electrons 9.10938291*10^-31 kg
protons 1.67262178*10^-27 kg
neutrons 1.6749*10^-27 kg
the mass of electrons is way smaller than both, the mass of protons and neutrons
therefore, 1) the mass of 2 electrons is the smallest
