maybe i think so
Heat is a form of energy. Atoms of a certain material begin to tremble very fast when heated and pass this movement on to other atoms. So I think -not shure, heat/ energy can only be passed through material, and so it is not possible in a vacuum.
Yes, heat can pass through a vacuum by radiation. All objects emit thermal radiation, which can travel through a vacuum without the need for a medium. This is how the Sun's energy reaches the Earth through the vacuum of space.
Light acts as a particle.

A vacuum
Electromagnetic waves, such as visible light, radio waves, and X-rays, can pass through a vacuum because they do not require a medium for propagation. However, mechanical waves, like sound waves, cannot propagate in a vacuum because they need a medium (such as air, water, or solids) to travel through.
Refractive index is the ratio of speeds.
Light does not pass through an opaque surface. (That is the basic definition of "opaque"). Heat will be absorbed (or rather the energy of the impinging radiation - including the light) will heat the opaque surface and underlying substrate and this heat will be re-emitted (in all directions). So in a way the heat will "pass through" the opaque surface but it really is absorbed and sent back out later.
In space both dark matter and dark energy are believed to be in the vacuum. The general answer is nothing-but light rays can pass invisibly through it.
Only by radiation. Infrared waves waves don't require a material medium to pass through. Heat energy is transmitted even through vacuum in the form of infrared waves. We get heat energy from sun in this way.
Yes it can. Think of the sun. I think it's via radiation.
Yes, all electromagnetic waves can pass through vacuum because they do not require a medium to propagate. This includes visible light, radio waves, microwaves, and X-rays.
