Question

Which method of heat transfer takes place when particular of matter vibrate and collide with each other in direct contact?

Conduction
Convection
Insulation
Radiation

Answer 1

CONDUCTION

step by step:

Conduction occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules.

Answer 2

Conduction - by touch
Convection - hot air rises, cold air sinks
Insulation - to insulate or capture heat
Radiation - by waves
Direct contact means touch, therefore the answer would be conduction.
