some solids,liquids and gases are dangers some are not dangers
Liquids are made when gas particles move closer together. Solids are made when liquid particles move even more closely together resulting in something along the lines of a frozen block of ice.
Frozen milk has more mass than non frozen milk because of how liquids freeze. If you think of it, solids have more mass than liquids because of how tightly packed the molecules are. Just like water, frozen milk will have a larger mass than non-frozen milk.
Solids have a set volume. Liquids have a set volume. Gases do not have a set volume. Why? Solids are solids. They don't move. They're in a 'frozen state' as is. Liquids 'mold' to the shape of their container and they stay there. Gases are free to go anywhere. Always moving and 'flying.'
Solids, liquids, and gases are considered matter because they have mass and occupy space. Matter is anything that has mass and takes up space, and solids, liquids, and gases all meet these criteria.
The motion of particles in gasses, liquids, and solids are all different. Gas particles can move much more quickly than solids.
Solids to Liquids (Melting) Liquids turning back into a Solid (Freezing) ((SCF))
Not all liquids have lower densities than all solids. Low density solids frequently contain air or other gasses as part of their makeup (cok, Styrofoam, etc)
