Answer 6

Have you read the definition of conduction ?

Answer 7

yea

Answer 8

* the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.

Answer 9

Okay. Let's check the answers then

Answer 10

a) the transmission of heat across matter

Sure thing. Says right here:

"the process by which heat or electricity is directly transmitted through the material of a substance"

"the process by which heat is transfered through matter

b) the electromagnetic radiation from the surface of an object which is due to the object's temperature

That's thermal radiation.

c) the transmission of heat across empty space

That's heat transfer.

d) the transfer of heat by currents within a liquid or gas

That's the same thing.
