Which types of heat transfer that allows heat to flow from hot objects to colder object? a. convection, but not conduction or radiation b. convection, conduction, and radiation c. convection and radiation, but not conduction d. convection and conduction, but not radiation.

I think the correct answer from the choices listed above is option D. The types of heat transfer that allows heat to flow from hot objects to colder object are convection and conduction, but not radiation. Convection and conduction heat transfer happens only when a medium is present while radiation do not need a radiation to occur.

2. they have negligible mass.

Ithink the answer is d i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
