There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
conduction, convection, and radiation
Heat transfers. The hotter loses heat energy to the cooler.
Yes, if they are colder than the air outside, they gain heat because of passive transport. Any object can transfer heat if there are heat differences between objects.
heat travels to any colder object
the process of transfer of heat energy in solids is known as conduction.. For more info-- the process of transfer of heat energy in liquids and gases is known as convection.. And the process of transfer of heat energy without any material medium is known as radiation..
Actually, there isn't any heat transfer when a fan is blowing. But, if you really need the answer, the closest one would be radiation.
any where but condition is there should be temperature difference
Any material that allows heat or electricity to transfer easily.
The convective heat transfer of any fluid is dependent on its velocity, viscosity...and other properties. The higher the velocity the higher the coefficient. Generally indoor convective heat transfer of air is approximately 40 W/m2.K It varys depending on wind conditions, generally within the range of 10-100 W/m2.K
Conduction, convection ,radiations are three methods of heat transfer. Conduction is carried out by direct contact with materials covection & radiation are carried out without any contact with the material
Any type.
It does contain heat energy. Usually not enough to transfer to its surroundings but a lot more than liquid nitrogen, for example.
Due to nuclear reaction in the sun it emits enormous heat ,and heat does not require any medium to transfer.
