How do conduction and convection differ? conduction can move through empty space to transfer heat; convection cannot. conduction does not require objects to have direct physical contact; convection does. conduction requires objects to have direct physical contact; convection does not. conduction transmits heat through electromagnetic waves; convection does not.

The correct answer is C. Conduction requires objects to have direct physical contact; convection does not.

*Conduction is heat transferred by touch, convection is heat transferred by currents (the heat rises, then it cools and falls, and becomes hot again*
Hope this helps!!

Answer 3, conduction requires physical conduct, convection does not.
