Question

When heat is transferred by the
movement of particles it is called..

Answer 1

convection

Step-by-step explanation:

Convection is a mode of heat transfer in which the molecules near the heat source get heated up, expand, become less dense, and rise upwards. The cooler molecules, on the other hand, sink to the bottom and are eventually heated up. Thus the transmission of heat by the movement of heated particles is called convection.
