Answer: The transfer of heat is through heated solid substance, in conduction, whereas in convection the heat energy is transmitted by way of intermediate medium.
In conduction, heat transfer takes place 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 occurs due to the difference in density.
Heat transfer is the process of transfer of heat from high temperature reservoir to low temperature reservoir. In terms of the thermodynamic system, heat transfer is the movement of heat across the boundary of the system due to temperature difference between the system and the surroundings.
Convection is the transfer of heat from the hotter parts of a liquid (or gas) to its colder parts by the movement of the liquid (or gas) itself. The transfer of heat by convection can take place only in liquids and gases because the particles in liquids and gases can move about freely.
Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.
Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. … Convection is usually the dominant form of heat transfer in liquids and gases.
Large-scale surface ocean currents are driven by global wind systems that are fueled by energy from the sun. These currents transfer heat from the tropics to the polar regions, influencing local and global climate.
Ocean currents are like rivers of water moving through the sea. Some currents are caused by convection, while others, called surface currents, are driven by wind. These currents move water all around the earth, bringing warm water to cooler areas and vice versa.
Here are some examples of different types of radiation:
How does heat travel along a metal? By conduction. This means that atoms of the metal become more energetic when heated, and they transfer this energy from atom to atom, so it travels along the bar from the hot end to the cooler end .
There are three ways heat is transferred into and through the atmosphere: radiation. conduction. convection.
A conductor is a material that allows internal (thermal) energy to be transmitted through it easily. All metals are good conductors. … Energy is passed on through the metal by these collisions, transmitting the energy. More frequent collisions increase the rate of transfer.
The influence of the flow of currents usually depends on the level of saltiness of the water, the rotation of the earth, the topography of the land and the orientation of the wind. It is these that bring cold water to the surface of the earth from the depths, and in the process forcing away the original surface water.
Explanation: Surface currents play a large role in determining climate. These currents bring warm water from the equator to cooler parts of the ocean; they transfer heat energy.
