Question

Which transfers heat from one object to another without transferring matter?

A. conduction

B. insulation

C. thermal expansion

Answer 1

Insulation prevents transfer of heat.

Thermal expansion is one effect of transfer of heat.

Conduction is one of the three ways to transfer heat, and one of the two ways to do it without transferring matter. (A)

Answer 2

A. Conduction

Step-by-step explanation:

Heat is transferred from one object to another but does not involve the movement of particles between the two objects. The only condition for this to happen is for the objects to be in contact. Contact ensures that adjacent particles transmit energy between them. It is measured in watts per meter per kelvin W/mK
