No it is a compound.
Solution
heterogeneous/colloid
Not unless it is a reversible reaction (Such as the Haber Process). If it is not reversible, you cannot get the same substances back.
A reaction which cannot be reversed is called an Irreversible reaction.
No, once an egg is cooked, it cannot be reversed or turned liquid again. The proteins in the egg react to heat by solidifying; this is an "irreversible colloid." By contrast, gelatin that becomes solid when chilled then melts when warmed is a "reversible colloid."
Yes, whipped cream is a colloid.
A gel is an example of a colloid. A colloid cannot be separated in the same way as a suspension can.
No it is a compound.
It depends what kind of colloid for example milk will not, it is a colloid but it doesn't set... Others may just depending on what kind your talking about
A Bunsen burner is an object: it is not a process of any kind.
solid solution
No it is not a colloid. Colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspension.
