Question

State the direction of heat transfer by way of convection.
answer me immediately

Answer 1

By the process of convection, heat is always transferred vertically upwards. The reason is that medium particles near the source of heat absorb heat from the source and they starts moving faster. As a result, the medium at this place becomes less dense so it rises up and the medium from above being denser, moves down to take its place. Thus, continues till the entire medium acquires the same temperature.
