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.
Heat and light energy travel through space and matter
As a matter of fact, it can.
A change in the state of matter occurs when heat energy is added or removed.
If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).
None of the above. Heat is energy, not matter.
Matter in any state can be propelled as fast as you want.Answer:Within the relativistic Universe matter can go as fast as the speed of light (with great difficulty). Excluding tachyons which (if they exist) the only matter observed to go at the speed of light are photons. Photons do not fall into the normal solid, liquid or gas states of matter as they have both wave and particle characteristics and no rest mass.For normal matter, the problems with acceleration require that the lightest particles will travel fastest for any amount of acceleration energy. This would call for the dissolution of the matter into individual atoms (into a gas) and the acceleration of the individual atoms.In this roundabout manner gases can be accelerated the most so the can travel the fastest.
solid, metallic
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
This is a gas.
Heat or cool it.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
