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: -Heat transfer in fluids generally takes place via convection. Convection currents are set up in the fluid because the hotter part of the fluid is not as dense as the cooler part, so there is an upward buoyant force on the hotter fluid, making it rise while the cooler, denser, fluid sinks.

Detailed explanation-3: -Convection is the transfer of heat in air or a fluid through currents. An example is a pot of water warming up on a hot stove. As it heats up, the particles spread out and become less dense. The warm water on the bottom of the pot rises and displaces the cold water.

Detailed explanation-4: -Convection is the transfer of thermal energy by the movement of a liquid or gas. Convection works when a liquid or gas is unevenly heated. Hot liquids (and gases) are less dense and rise, causing. The warmer section of the material will rise while the cooler part sinks.

Detailed explanation-5: -Convection is the process by which heat is transferred from a solid surface to a nonsolid, such as air or water. The convection process involves the motion of the fluid relative to the solid surface and the processes by which heat is transferred across the interface.
