Question

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.

Answer 1

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

Answer 2

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!!
