Change of Phase between Gases and Solids
Solids that transform to gas must first pass through a liquid condition. Solids may, on the other hand, transform from solid to gas without passing through the liquid state. The opposite change can also happen. Gases can sometimes convert straight to solids.
Change of State of Matter
When cubes of ice melt into water or liquid boils into vapor, you may have seen changes in states of matter, but have you ever wondered why the substances change their form? When matter loses or gains energy, it changes its condition. When a substance gains energy, its molecules or atoms move faster, and extra kinetic energy pushes the particles at a sufficient distance apart from one another that their shape changes. Typically, this energy is called thermal energy or heat. Let us look at the science supporting the shifting states of matter in this post.
