Detailed explanation-1: -The heat energy can be transferred by the process of convection by the difference occurring in temperature between the two parts of the fluid. Due to this temperature difference, hot fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called a convection current.

Detailed explanation-2: -Convection happens when there is a difference in temperature between two parts of a liquid or gas. The hot part of a fluid rises, and the cooler part sinks.

Detailed explanation-3: -Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. As this happens, cooler liquid or gas takes the place of the warmer areas which have risen higher. This cycle results in a continuous circulation pattern and heat is transferred to cooler areas.

Detailed explanation-4: -Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.

Detailed explanation-5: -Heat Transfer: The movement of heat from a warmer object to a colder one – when two substances at different temperatures are mixed together, heat flows from the warmer body to the cooler body until they reach the same temperature (Zeroth Law of Thermodynamics – Thermal Equilibrium).
