What else can I help you with?
Does Heat require a medium?
No, heat does not require a medium to travel. Heat can be transferred through conduction, convection, or radiation, and can travel through a vacuum as well.
Does heat travel through space by convection?
No, convection requires the movement of particles. Since space is a vacuum, there are no particles present.
Can heat radiation travel through a vacuum?
Yes, heat radiation can travel through a vacuum because it does not require a medium for transfer like conduction or convection. This is why the Sun's heat can reach the Earth through the vacuum of space.
What does heat and light travel in?
Heat can travel through conduction, convection, or radiation. Light travels in waves, specifically as electromagnetic radiation, which can move through a vacuum or a medium.
Why heat cannot reach the earth from the sun by conduction or convection?
Heat from the sun cannot reach the earth through conduction or convection because space is a vacuum and does not contain matter to transfer heat. Heat from the sun reaches the earth through radiation, as electromagnetic waves travel through the vacuum of space.

Can heat energy travel through space a vacuum by convection?
Actually heat cannot travel through vacuum. sun emits radiations (obviously electromagnetic radiations.) which needs no medium to travel. hence these radiations travel through space and reaches earth where it interacts with atmosphere. when these radiations fall on media like air, water land etc. the radiation is converted into heat energy. Thus it is clear that heat from sun is converted into radiations which travel through space and reaches earth where it is converted to light.
Why heat cannot reach the earth from the sun by conduction or convection?
Heat from the sun cannot reach the earth through conduction or convection because space is a vacuum and does not contain matter to transfer heat. Heat from the sun reaches the earth through radiation, as electromagnetic waves travel through the vacuum of space.
Is it possible for heat to flow across a vacuum?
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.
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.
Why does convection not happen in a vacuum?
Convection requires a medium, such as a gas or liquid, to transfer heat through the motion of the medium itself. In a vacuum, there is no medium to carry the heat, so convection cannot occur. Heat transfer in a vacuum primarily occurs through radiation.
Does heat travel in a vacuum?
Lets look at a vacuum and heat. Heat is the treansfer of energy from one piece of matter to another. A vacuum is the absence of matter. Heat cannot transfer in a vacuum because there must be matter in close proximity to other matter for heat to travel.
explain how heat transfer can be minimised by convection in a vacuum flask?
Heat transfer by convection can be minimized in a vacuum flask because there is no air (or fluid) inside to carry heat through convection currents. The vacuum creates a barrier that reduces heat transfer by convection, as there is no medium for the heat to move through. This helps to keep the contents of the vacuum flask at their original temperature for a longer period of time.
Does heat from the sun travel through space by convection?
For convection current we need a material medium. But in between sun and earth there is almost vacuum. So heat transfer is mainly due to phenomenon of radiation. That too electromagnetic waves are being propagated right from the sun and stars.
