Answer:
C.) crystalline solids
Explanation:
The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.
The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.
Answer:
29.2 m
Explanation:
P=mh. Plug in the values.
584 J = 20 kg x <em>h</em>
h = 29.2 m
If it's gravitational potential energy multiply is by gravity which I think is 10 m/s.

Answer: Carbon is one of the essential gases in nature,couple of natural processes causes the release of carbon. Some of the processes include;
- When the remains of producers are broken down by decomposers in the ecosystem.
- When animals break down food molecules to obtain energy, carbon is released.
- When the remains of consumers in the ecosystem are broken down by soil decomposers, carbon is released.
