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.
Solution
In this case a solution is formed.
A liquid in which something has been dissolved is usually referred to as a 'solution'.
The change of a substance from solid to liquid is called melting. This process occurs when heat is added to the solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely, transitioning it to a liquid state.
solid liquid
Solution
In this case a solution is formed.
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
The solid being added to the liquid is called a solute. When the solute is dissolved in the liquid, it forms a solution.
Carbon changes from gas, to liquid, to solid form, and never disappears, so in that sense it is renewable.
when a solid disappears in the solution we can say the solid?
When energy is added to a solid, it can reach its melting point where it transitions from a solid to a liquid.
A liquid in which something has been dissolved is usually referred to as a 'solution'.
solid is it?
LIQUID
heat
well i do not everyone
