What is the only way heat travels through a vacuum?
by radiation - convection and conduction cannot occur in a vacuum!
How does the temperature remain constant in a vacuum flask. Explain why in can do so over a long period of time?
Vacuum is a great insulator, because there needs to be some medium for processes of conduction or convection to occur. The only possible way to transfer heat through vacuum is radiation, which is not as effective, especially that flask walls are also constructed to limit radiation heat transfer(they are reflective). Temperature stays the same if there are no means to transfer energy between interior end environment.
How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped
How can Heat can be transferred through a vacuum?
There are three ways to transfer heat:1. Conduction 2. Convection 3. Radiation Only the third way works in the case of a vacuum. In this third way, the radiation in question is electromagnetic waves - usually infrared (it depends on the temperature of the object). Just like light - which is also an electromagnetic radiation - other electromagnetic waves travel especially well through empty space.
Why can't heat travel from the sun by convection or conduction?
Because there are no atoms to collide with to transfer the heat energy from the sun, thus, there is no conduction. This is also the same reason that there are no convection currents in space; There are no atoms to collide with to transfer heat. Thus, the only possible way to transfer heat is by radiation.
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.
Can heat travel through a vaccume by radiation only?
Rradiation is the only way that heat can travel in a vacuum.

How do you insulated thermos?
Um......your question is worded oddly, but the way an thermos is insulated is by having a vacuum between it's two flasks. The vacuum causes heat transfer to reduce greatly.

Why does a vacum make a good insulator?
The only way to move heat energy in a vacuum is via radiation.
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.

Heat can be transfered by conduction or convection?
By both way. Conduction is the basic of heat transfer, the energy (heat) is transfer from molecule to molecule from different in temperature gradient. Concept of convection is when there is motion of molecule come to concern like wind blow and take away the heat rapidly. Convection heat transfer can only occur in fluid state e.g. liquid and gas. In solid, only conduction heat transfer taken place.

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.
