Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.... read more ›
Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather.... read more ›
Answer. Everyday Examples of Convection Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator - Puts warm air out at the top and draws in cooler air at the bottom.... read more ›
Convection is a way in which heat travels. It occurs when heat is transferred by the movement of liquids or gases. The other methods of heat transfer are conduction and radiation. Natural convection occurs when fluids are heated.... see details ›
Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.... see details ›
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together than in gases, where particles are further apart.... read more ›
forced convection - When a fan, pump or suction device is used to facilitate convection, the result is forced convection. Everyday examples of this can be seen with air conditioning, central heating, a car radiator using fluid, or a convection oven.... read more ›
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.... see details ›
In conduction, heat transfer occurs between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles. The heat transfer takes place due to the difference in temperature.... continue reading ›
Examples of Conduction
A lizard warming its belly on a hot rock. Touching a hot seatbelt when you get into a car. A blacksmith heating up a sword in hot coals, and the heat transferring up through the metal. The heat from a stovetop transferring into a metal pot of water.... see more ›
On Earth, water boils via natural convection. To simplify a bit, boiling is actually a very efficient heat transfer process and, in this case, boiling transfers the heat from the fire on your stove to the water that will cook your pasta.... continue reading ›
- Heat from the sun warming your face.
- Heat from a lightbulb.
- Heat from a fire.
- Heat from anything else which is warmer than its surroundings.
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.... read more ›
Conduction transfers heat within a body or between two bodies that are touching. It is a point-by-point process of heat transfer. Conduction occurs in solids, liquids, or gases that are at rest.... read more ›
- The velocity of the liquid and gaseous substances.
- Nature of viscosity (high or low) of the fluids.
- Rate of heat flux of the transfer.
- Roughness nature of the surface.
There are two types of convection: natural convection and forced convection. Natural convection is produced by density differences in a fluid due to temperature differences (e.g., as in “hot air rises”). Global atmospheric circulation and local weather phenomena (including wind) are due to convective heat transfer.... read more ›
Natural convection is a mechanism of heat transportation in which the fluid motion is not generated by an external source. Instead the fluid motion is caused by buoyancy, the difference in fluid density occurring due to temperature gradients.... see more ›

Conduction is a process in which transfer of heat takes place between objects by direct contact. Convection refers to the form of heat transfer in which energy transition occurs within the fluid. Radition alludes to the mechanism in which heat is transmitted without any physical contact between objects.... continue reading ›
Whereas conduction is a static process, convection is a more efficient method of heat transfer because it adds the element of motion. A convection oven heats food faster than an ordinary one because it has a fan that blows the hot air around.... read more ›
