In matter heat is the vibration (kinetic energy) of atoms or molecules and propagates in matter by means of conduction and convection.
Heat is also radiation and part of the electromagnetic spectrum which includes visible light. Thus heat and light are propagated in a vacuum as radiant energy, synchronized oscillations of electric and magnetic fields that propagate at the speed of light.
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
The heat energy comes from the Sun to us via electromagnetic radiation, mainly light, which can propagate through empty space.
Gravitational waves propagate at the speed of light. Any change in the distribution of masses will propagate at that speed.
Electromagnetic waves, like light, do involve changes in the electric and the magnetic field. These changes propagate at the speed of light - as a wave.Electromagnetic waves, like light, do involve changes in the electric and the magnetic field.

Sound will propagate through any matter, but not a vacuum, light will propagate through a vacuum, but only through transparent matter.
It is not very clear what the question means. Light is an electromagnetic field and it can propagate in a vacuum. Propagation of a beam of light is unaffected by any other electromagnetic fields in its path.
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.
Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light. Therefore, he also suspected that light was an electromagnetic wave. This was confirmed later.Yes, more or less. James Clerk Maxwell predicted that an electromagnetic wave would propagate at the speed of light.

Basically, light is NOT a mechanical wave, which would require matter; it is an electromagnetic wave, which means that disturbances in the electric field and the magnetic field propagate. This requires no matter; such fields exist - and can propagate - in empty space.
Energy in the form of heat and light is released.
Nothing. It continues to propagate at the speed of light, and is not diffracted or distorted except by negligible gravitational effects.
Nuclear fusion releases energy as heat.
