In the scientific topic of heat transfer, convection, conduction and radiation are of vital importance. Convective heat, for example, is the transfer of heat by the movement of fluids. What do you know about it and the rest of this transfer methods.
Answers
Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature. Warm air is less dense than cold air, and so convection currents can form in the presence of a temperature gradient.
conduction :- The transfer of energy, such as heat or an electric charge, through a substance.
Radiation :- radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation
Answer:
Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass.
Explanation:
CONVECTION: is the transfer of heat from one place to another by the movement of fluids. Convection is usually the dominant form of heat transfer in liquids and gases
CONDUCTION: occurs when two object at different temperatures are in contact with each other. Heat flows from the warmer to the cooler object until they are both at the same temperature. Occurs only when objects are in contact .
RADIATION : is a method of heat transfer that does not rely upon any contact between the heat source and the heated object. Heat can be transmitted though empty space by thermal radiation.
