How is radiation different from the other types of heat transfer?

∙ 10y ago
The question asks only about the differences between radiation heating and convective heating. Refer to other answers concerning a description of these two types of heating. The differences between radiation and convection are:
- In radiation heating, the radiation itself is the source (but not necessarily the only source) of thermal energy, whereas in convection heating, a separate, external source is required to create the convective currents - that is, the currents themselves are not the source of the heat, they only transport the heat throughout the liquid being heated.
- Radiation heating can occur at distance - a heat lamp, for example, can keep something warm without coming into contact with the substance. In convection, the warmer and cooler liquids must be in contact with each other in order to create convective flow.
- Radiation will heat plasma, gas, liquid, or solid. Convection works only on liquids, including gasses.
- Radiation does not require a medium - light can pass through a vacuum and still heat up the target object. Convection requires a liquid medium through which heat can transfer through motion of the liquid.
- Radiation requires no motion of the target object in order to heat that object. Convection, by definition, requires the warmer liquid to rise and the cooler liquid to sink in order to create convective currents.
- Radiation will heat an object in a weightless or zero gravity environment. Convection cannot occur in a weightless of zero gravity environment, because there is no 'up' or 'down' in such environments in which a convective current can flow.
- Radiation tends to heat objects from the outside in. Convection tends to heat things from the bottom up.

What are 3 types of heat transfer?
convection conduction radiation
What are the three types of heat transfer in the atmosphere?
Convection, conduction and radiation
What is the type of spectrum of all types of radiation called?
There are different types of radiation; you may be referring to the electromagnetic radiation.
How is it possible for a single electron to produce so many different wavelengths and frequencies?
A single electron can produce different types of radiation. Radiation, frequency, and wavelength all rely on each other. If an electron can produce multiple types of radiation, it can also produce different wavelengths and frequencies, because the wavelengths and frequencies are dependent on the radiation type.
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.
Are there any other types of heat transfer?
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
What are 3 types of heat transfer?
convection conduction radiation
What transfers radiation?
It can transfer energy-eg heat energy. Other types of heat transferance are conduction and convection
What are the three types of heat transfer in the atmosphere?
Convection, conduction and radiation
What is the type of spectrum of all types of radiation called?
There are different types of radiation; you may be referring to the electromagnetic radiation.
What form of heat transfer is caused by the greenhouse effect?
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
How are radiation and convection similar?
Both are types of heat transfer without contact.
What transfer energy through empty space is called?
Transferring energy through empty space is called radiation. There are three types of energy transfer: conduction, convection, and radiation. Radiation is the only energy transfer that does not require a medium. Radiation is a wave of pure energy; one example of radiation is the sunlight that reaches Earth, which is electromagnetic radiation.
How is it possible for a single electron to produce so many different wavelengths and frequencies?
A single electron can produce different types of radiation. Radiation, frequency, and wavelength all rely on each other. If an electron can produce multiple types of radiation, it can also produce different wavelengths and frequencies, because the wavelengths and frequencies are dependent on the radiation type.
Are different types of electromagnetic radiation fundamentally different types of waves?
No, this is a false statement.
What determines the different types of radiation?
YES
How many kind of heat is there?
Think you mean types of heat transfer? Radiation, Convection, and Conduction.
