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

C. Conduction requires objects to have direct physical contact; convection does not.
