Ineed all the answers to all of them today cause i have to give it in today

Solids tend to have heavy weights and can sometimes float also you cant stick something through them unless its puddy or playdough also they have a definite shape and volume.

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
and amorphous solids are any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern. Such solids include glass, plastic, and gel. Solids and liquids are both forms of condensed matter; both are composed of atoms in close proximity to each other.

liquids dont have a definite shape but they do have volume though they are usually runny or watery .

a needle can float because it is has less density than water

a gas has no definite shape or volume and are most times invisible to the eye

Elias is almost correct. he just got it backwards.the correct answer is that it demonstrates elastic potential energy transforming into kinetic energy.
