What is an example of solar radiation?
The sun is the best example of radiation because, of the three processes of heat transfer (conduction, convection, radiation), the sun only radiates heat energy.Conduction occurs through matter, and we are separated from the sun by an absence of matter (vacuum).Convection is the movement of a fluid, carrying heat. Although there is a solar wind, it is very very tenuous - a vacuum.You can step outside and feel the sun's radiation (infrared) on your skin, see the light with your eyes.
Heat transfer by conduction occurs when?
heat transfer is made ways of three like conduction, convection, and radiation. conduction is done by the physical contact between two parts with one another( in the medium of solid). conduction due to lattice vibration or lattice-free election by the increasing kinetic and internal energy of metal.
The way heat reaches the moon?
Since the space between the moon and other objects is essentially a vacuum, the only feasible mode for heat transfer is by radiative heat transfer.
Why is vacuum a good insulator?
A vacuum is a good insulator because it prevents the transfer of heat by eliminating the medium (matter).A perfect vacuum is the absence of matter. Heat is transferred by conduction, convection and radiation. Radiation is the only form of heat transfer that does not need a medium. Furthermore, radiation is generally the least efficient method of heat transfer.
Does convection occur in the core of a star?
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
What type of heat transfer is it when we receive sunlight?
It is radiation, as that is the only heat transfer that can occur in a vacuum (the universe).
How is heat transfer by radiation different form heat transfer by convection and conduction?
Radiation requires neither contact (through which conduction transfers heat) nor mass flow or movement (through which convection transfers heat). Only radiation can take place in a vacuum. Convection and conduction both require a material medium for the heat transfer to occur. Only radiation can transfer thermal energy through the vacuum of space.
What are the different types of heat transfer?
There are three types of heat transfer, namely conduction, convection and radiation. Heat is transferred until the reach a state of equilibrium. Conduction is basically the transfer of heat through a surface of contact, such as a fire to the base of a pot. We say that a material is a good or poor conductor of heat when heat travels quickly or slowly in that particular material. Good conductors of heat are metals whereas poor conductors of heat are rubber and Styrofoam. Conduction cannot occur in a vacuum. Convection is the transfer of heat through molecules. It can only occur in liquids and gases as there are relatively big spaces between the molecules. A convection current is where hot air rises and cold air sinks. Convection cannot occur in a vacuum. Radiation is the transfer of heat through a vacuum. Heat is transferred from the Sun to Earth through radiation.
How is radiation different than other methods of energy transfer?
Radiation is the only method of energy transfer that can transfer energy like heat through space.
How does a heat transfer occur?
only from warm objects to colder ones.
What method of heat transfer makes possible for the sun to heat earth?
radiation, this is the only one that travels in a vacuum
Heat transfer by radiation is the only method of heat transfer that can travel through a vacuum. What is a vacuum?
A vacuum is a space where there is no, or very little matter (ex. air molecules). One example of a vacuum is outer space. Because there is no matter for heat to travel through via convection or conduction, radiation is the only heat transfer that can take place in a vacuum.
What is the only method of heat transfer that does not rely upon any contact between the heat source and the heated object?
Radiation
What is the only way heat travels through a vacuum?
by radiation - convection and conduction cannot occur in a vacuum!
How would it be possible that there could be high temperature but no heat transfer?
Heat transfer will only occur if there is a difference in temperatures. So if an object is high temperature but the surrounding area is also high temperature there will be no heat transfer.
What is one example of heat transfer through radiation?
Heat transfer through radiation is probably best illustrated by the warming of the earth by the sun. Electromagnetic energy from the sun in the form of light travels through the vacuum of space to reach the earth and warm us.
What are three example of heat transfer in a paragraph?
Heat can only be transferred by radiation, convection or conduction. Heat will not travel though or in a "paragraph" which is just a literary construction.
