Heat transfer occurs because in nature things are driven towards a point of equilibrium (all things being the same). This is expressed in the second law of thermodynamics which is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system.
Heat transfer happens in one of three ways.
1 --- Conduction (direct transfer of heat by one object in contact with another)
2 --- Convection (heat moving by means of air)
3 --- Radiation (light energy).

∙ 11y agoheat is transfered in three different ways:
radiation
condensation
and convection
condensation is from gases and steam
convection is by touch
and radiation is by light

∙ 12y agoThermal heat is transferred by heating one molecule and having it spread the thermal heat to its neighboring molecules, which spread the thermal heat to its neighboring molecules and so on, until the thermal heat is spread throughout the element.

The transfer of heat by fluid?
The transfer of heat by fluid is convection.
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
What is the difference between heat transfer and mass transfer?
Heat transfer deals with the movement of heat and temperature gradients. The three types of heat transfer are conduction, convection, and radiation. Mass transfer deals with concentrations of a particular substance. Types of mass transfer include diffusion and convection.
How can heat transfer in liquids and gases be reduced?
Insulation will reduce heat transfer.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
Winds transfer heat energy by what method of heat transfer?
convection
Is convection the main type of heat transfer?
No, in the universe radiation heat transfer is by far the largest transfer.
Is conduction a heat transfer by direct contact of particles of matter?
Yes, whereas convection heat transfer is the transfer of heat via a liquid, and radiative heat transfer occurs through empty space (like the heat you feel from the sun).
What is heat transferred in?
Radiation in heat transfer is one of three known modes of heat transfer: conduction (as heat transfer in solids and less effective in liquids)), Convection (as in liquids and gases), and radiation (that not necessarily require a medium for the transfer). Heat of sun is transferred to us in the vacuum space by radiation heat transfer.
