All parts of the rod are in thermal equilibrium with each other. We can assign a temperature to the rod. WebWe can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another. We can exemplify it by observing that we feel hotter when we place our hands above a campfire. This happens due to convection currents. Convention in Air
