a convection.
b connection.
c correction.
d conduction.

So the question is what is a transfer of heat within a liquid or gas that involves warm particles moving in currents. So there are three mechanisms of moving heat. Those are convection, conduction and radiation. Radiation is transfering energy via electromagnetic waves. Conduction is transfering heat trough some thermal conductor. Convection is transferring heat within a liquid or gas that involves warm particless moving in currents.

It won't lose or gain electrons if it's a covalent bond it shares the electrons with another atom or atoms. if it is an ionic bond it will lose the 3 electrons on the outer shell and become a positively charged ion.  credit goes to @sunshinebaby of answers.yahoo.com.
