Solids do not evaporate, they Sublimate, i.e. they go directly from the solid state to a vapor. An example this process would be if you gently heat Iodine crystals, you will see purplish vapors begin to form ... it's sublimating.
CAUTIONIf you try this, do it only in fume hood and with a very small sample of Iodine. The fumes are poisonous!solids disappear because when the temperature is risen the atoms in a solid separate causing the solid to tern into a liquid.
plants and animals that die seem to disappear because it causes danger for the person or children
Very much a solid. If it were a liquid it would slide out of (and over and around) your fingers when you tried to grasp it. If it were a gas it would quickly mix with the air and you'd never find it - then again I do seem to be losing track of a lot of pencils so.... :-)
Freezing. It may seem strange, because things that 'freeze' are not necessarily cold, but the temperature at which something becomes a solid is its 'freezing point'.

A solid is a state of matter. Solids don't readily mix.Particles never actually disappear.You can lose them in fluid if they readily dissolve in that fluid. When dissolving, the particles may break up (ionize) and you could probably call that "disappearing". Some solids will absorb gas particles. For example, concrete can absorb oxygen molecules. But the oxygen is still there, it hasn't disappeared, just been absorbed.Concrete is a mixture and oxygen can be absorbed by it so it would seem the answer is "yes". However, this is kind of skewing the original question a bit.Short answer: No, particles never disappear.
Gas...The molecules are less tightly packed together like in a solid and liquid so they're free to move. They seem more energized, they're faster.

You seem to have the view that to be "matter" something has to be solid. This is NOT the case, everything is made of matter which can come in various states :- Solid, Liquid, Gas, Plasma.
Sublimation is a form of state transition or phase change. It is the process where a solid changes states and turns directly into gas without passing through a liquid state.Dry ice is a good example of a substance that undergoes sublimation. We can watch a chunk of the white solid "disappear" without liquefying.Another example: Under certain conditions, snow on the ground will seem to slowly disappear as it changes directly into water vapor, bypassing the liquid phase.In lower grades it is sometimes accepted that sublimation can also be when a gas turns straight into a solid without going through a liquid state but that transition is formally known as deposition. You can remember this by saying solid-gas sublimation because they both start with s!See Related Links for more information.
Which gas? There are lots of them. Gas is a stage of matter (solid, liquid, gas) not what you seem to think it is. So your answer is - who knows.

The correct spelling of the word is disappear.Some example sentences are:My keys seem to disappear often, as if they have legs.Where did the waiter disappear to?Much to the audience's disappointment, the magician's assistant did not disappear.
No, although it may seem counter intuitive, freezing is an exothermic process. In order to go from a liquid to a solid phase a substance must lose energy. This energy is released to the surroundings.
Balloons are solids. They are filled with gases.
