There are three modes of conduction of heat :-
1.conduction
2. convection
3. radiation
heat flow through vacuum comes under heat flow through radiation. Im this case heat acts as an electromagnetic wave , as these waves can propagate through vacuum energy is transferred even though there is no contact between the source and the drain(sink/destination .... whatever).
Note :- Actually we discussions pertaining to the matter weather vacuum is a good conductor or bad conductor are inappropriate as vacuum is not a material to discuss its properties, its just like asking give me a dozen of water(i am not intentionally sarcastic i just want to explain how weird it is to say that vacuum is a good conductor).
What else can I help you with?
Is a vacuum a good heat conductor?
nope
What metal is the poorest conductor of heat?
Vacuum
What is the most poor conductor of heat?
vacuum
Is berylium a good conductor of heat?
Very good. Used in vacuum tubes and barred recently from high tech electronics.
Is duct tape a good conductor of heat?
Duct tape is not a good conductor of heat. Its composition and thickness make it a poor conductor, so it does not readily transfer heat.
Is a pencil a good conductor of heat?
No, a pencil is not a good conductor of heat because it is made of graphite, which is a poor conductor of heat. Heat will not travel easily through a pencil, making it a good insulator rather than a conductor of heat.
Is boron a good conductor of heat?
Yes it is but it is not good for electricity!!
Is phosphate a good conductor of heat?
Phosphate is not a good conductor of heat. It is actually a poor conductor of heat due to its molecular structure, which hinders the transfer of heat energy. This property makes phosphate a good insulator rather than a conductor of heat.
Is milk a good heat conductor?
No, milk is not a good conductor.
Why is aluminum the worst heat conductor?
Aluminium is a good conductor of heat.
Is calcium a good conductor of electricity and heat?
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
What is a good heat conductor?
Copper and aluminum. Most heat sinks are made of Aluminum (cheap and a good conductor of heat).
