how can space be called a vacume?

Question

a vacume flask dosnt conduct heat ,
space does
a vacume is nessesary to evacuate matter in this dense atmoshere but space is rarefied [sans conductive matter],
on earth we need to empty our the gasses to duplicate the rarified conditions of space ,yet our thermose dosnt conduct heat and space 'vacume ' does.
can space thus be in truth [as a trueism] be called a vacume?

Answer 1

The answer of space and vacuum is the area between your ears ....if you cant spell properly then obviously you do not have the intelligence to do your own research and either looking for an opinion or someone to do your research.....i wont do your research but will give you an opinion........get a dictionary out
vacuum V A C U U M. and there endeth the lesson.

Answer 2

Heat is conducted by one of three means: radiation, convection, and conduction. Conduction can only occur if two objects of different heat / energy levels are in direct contact with each other. Convection can only occur if there is a fluid in which to transfer the heat (space is not a fluid). That leaves radiation. Radiation is the primary means by which energy is conducted through space, and radiation can indeed occur in a vacuum.

Answer 3

Space doesn't conduct heat. Electromagnetic radiation travels through space, however, and EM radiation is energy, which is essentially heat. Heat, or more generally, energy radiates through space more freely than through air because there is less "stuff" in the way.

When you stand near a fire, the front of your body will often feel very hot. This isn't from heat conducted by the air, but from heat radiated from the fire. The fire will heat up the air of course, but it is more gradual and certainly won't create such a strong gradient of warm air that it would feel hot in front of you and cold behind.

Answer 4

Who said space is a vacuum? It is not a vacuum.
