Yes. That is correct. It certainly does.
But I can hear mobs of readers right now, asking "WHYdoes convection need
a medium to travel ?", and their concerns must certainly be addressed.
The answer to that one is:
"Convection" is the term used to describe the transfer of heat by means of the
physical motion of a heat-carrying medium. No other process of heat transfer can
properly be labeled 'convection'. So the answer is: Convection requires a medium
to travel, because if there is no medium involved, then the process isn't convection.
And by the way, 'conduction' also involves a medium. The above discussion applies
equally well to 'conduction', if you just knock out the part where it says "... the
physical motion of ...".
What else can I help you with?
Why is there no heat transfer by convection or conduction through a vacuum?
Conduction needs a conducting medium. Convection needs something to convect. Neither exists in a vacuum.
Can heat travel by convection through a vacuum?
No. Convection requires a carrier to convey the heat. Vacuum says there is nothing to do the conveying. Radiation does not need a convector, so heat can travel by radiation through a vacuum, like the radiation from the sun.
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.
What is mechaincal energy?
The form of energy that needs a medium to travel is known as mechanical energy.For example sound needs a medium to travel,that's why sound can't travel in vacuum,light needs no medium to travel it is non mechanical form of energy.
What needs a medium substance to travel through?
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
Why can heat travel through space by radiation but not by conduction and convection?
For conduction and convection we need a material medium. But for radiation such a meaterial medium is not necessary. So in free space radiation can pass through easily.
Where do sound waves cannot travel?
it can't travel in a vacuum, it needs medium to travel
Sound will NOT travel through?
Sound needs a matter based medium, so it will not travel through vacuum.
What waves needs a medium to travel through?
Sound Wave
What does sound travel as in a medium?
It needs particles, so Air, Liquid or Solid to travel. so the medium is any particles, so if there is no particles, sound cannot travel.
Why doesn't radiation need a medium to transfer heat energy?
Radiation needs no medium to travel as it is a simple transmission of electromagnetic waves and here heat is transferred not by heating the particles alternatively as in conduction or convection but directly through waves.
What do conduction and convection do that radiation does notwhat does radiation use instead?
Conduction and convection badly needs material medium but radiation does not need a material medium as an essential one. It could traverse even in free space in the form of electromagnetic waves
