How is heat transferred through a vacuum?
Only by radiation. Infrared waves waves don't require a material medium to pass through. Heat energy is transmitted even through vacuum in the form of infrared waves. We get heat energy from sun in this way.
Can you hear in a vacuum?
No. Since there is no air in a vacuum and sound travels only with the presence of air, you can't hear in a vacuum.
Why is heat from the sun transferred through radiation?
Because radiation is the only method that works in 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 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 method of heat transfer makes possible for the sun to heat earth?
radiation, this is the only one that travels in a vacuum
Which mechanism of heat transfer can work in a vacuum?
Heat is a form of energy. Atoms of a certain material begin to tremble very fast when heated and pass this movement on to other atoms. So I think -not shure, heat/ energy can only be passed through material, and so it is not possible in a vacuum.
Does light slow down when it travels through matter?
Light slows down when it travels through matter.The only time light travels at is maximum speed, c, is in a vacuum.
Can heat travel through a vaccume by radiation only?
Rradiation is the only way that heat can travel 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.

How does heat travel throughteach state of matter?
Heat travels through waves of insulation through metals and other materials. The only metals that heat does not travel through are aluminum and nickel.
Can you hear in a vacuum?
No. Since there is no air in a vacuum and sound travels only with the presence of air, you can't hear in a vacuum.

Is vacuum the only medium for light to travel?
No. Light also travels through air, water and glass, to give just a few examples.
