There is no true vacuum in outer space (or anywhere!). Very very roughly, if something 'froze' in outer space, the 'energy' would convert into 'frozen matter'.
It is converted into "movement" if something is placed on the spring.
No, energy is conducted away from whatever is freezing.
Not much. When something burns, most of the energy is converted to heat.
Photosynthesis or respiration. For example, light is converted into glucose or energy for the plants
Methane can be used to create energy
Energy is neither used up nor destroyed, but it is converted into something else. In that way, it is conserved.

Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.
Chemical energy is converted into heat energy which is then converted into mechanical energy
Yes. This happens, for example, when steam is used to raise something like a balloon.
You need to get the energy OUT of the water; otherwise it won't freeze. This is usually done by putting the water in contact with something colder.
