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.
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.
Why does conduction not occurs at all in a perfect vacuum?
It is because sound travel from particles to particles.In vacuum,there is no material medium and thus no particle through which vibrations can travel from one end to the other.
Why does the energy from the sun travel to Earth by radiation instead of by convection or conduction?
Energy from the sun travels to Earth by radiation because space is a vacuum and there is no medium for convection or conduction to occur. Radiation is the most efficient way for heat to transfer through the vacuum of space.
What important ability or property does electromagnetic radiation have that other energy transport processes such as conduction and convection do not?
Electromagnetic radiation can travel through a vacuum (like the vacuum of space), while conduction and convection require matter to do their thing.
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 cant thermal radiation move through space by conduction or convection?
Because in space there are no particles (this is called a vacuum), however conduction and convection require particles to work eg. solids, liquids and gases have particle arrangements. So thermal radiation has to travel through space via radiation as space is a vacuum and particle-less.
Why is conduction not responsible for bringing heat to earth?
Conduction is the transfer of heat through direct contact. In the case of the Earth, there is no medium for heat to travel through via conduction since space is a vacuum. Instead, heat from the Sun reaches Earth through radiation, which does not require a medium.
Why can heat not travel by conduction through a vacuum when there is no particles?
Conduction requires the presence of matter. The way conduction works is that one molecule bumps into another molecule, transferring energy. This mechanism, obviously, requires the presence of molecules.
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.
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 the sun's heat not reach the earth by conduction or conviction?
The sun's heat reaches the Earth through radiation, not conduction or convection. Radiation is the transfer of heat energy in the form of electromagnetic waves, such as light and infrared radiation, which can travel through the vacuum of space to reach us. Conduction and convection require a material medium, which is not present in the vacuum of space.
