Question

how is convection different from conduction? a convection can transfer heat through a vacuum but conduction cannot. b conduction can transfer heat through a vacuum but convection cannot. c convection only takes place in liquids and gases but conduction transfers heat in mostly solids. d convection takes place only in solids whereas conduction transfers heat in liquids and gases

Explanation:

Conduction is heat - transfer through direct contact, mainly in solids. Convection is heat - transfer by the movement of fluids (liquids and gases) and cannot occur in a vacuum.

Answer:

C. Convection only takes place in liquids and gases but conduction transfers heat in mostly solids.
