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).
What else can I help you with?
What is the convective heat transfer coefficient of water and how does it impact the rate of heat transfer in a system?
The convective heat transfer coefficient of water is a measure of how easily heat can move through water. A higher convective heat transfer coefficient means heat can transfer more quickly. In a system, a higher convective heat transfer coefficient can increase the rate of heat transfer, making the system more efficient at exchanging heat.
What are the three heat transfer methods?
Conduction, convection and radiation ;)
What are the three methods for heat transfer?
The three methods of heat transfer are conduction (transfer of heat within a material or between materials in direct contact), convection (transfer of heat through fluid movement), and radiation (transfer of heat through electromagnetic waves).
What are t he three types of heat transfer?
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through physical contact, convection involves the transfer of heat through the movement of fluids or gases, and radiation is the transfer of heat through electromagnetic waves.
Heat transfer by fluids takes place by what?
Heat transfer by fluids can occur through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between molecules, convection is the transfer of heat by the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
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.

What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What are the three heat transfer methods?
Conduction, convection and radiation ;)
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.
