The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.

I hope this would be able to help u
dont forget the symbol its +2
Answer: No
Explanation: For it to be a divergent boundary, the arrows would have to be pointing in opposite directions. (one points left, one points right).
Answer:
Hg Pb are in one, Li and B and O are in one, and NaCl are in one, As is alone
Explanation:
Periods are horizontal
