From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)
<h3>The features of different states of Matter:</h3>
Matter is defined as anything that has weight and occupies space.
There are three states of matter that is in existence which include:
- Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.
- Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.
Therefore, a liquid occupies the shape of its container.
- Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.
Therefore, a gas neither has a definite shape nor volume.

Answer:
In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition. Although we call them physical "reactions," no reaction is actually occurring.
Answer:
energy = heat = producers = consumer animals =
decomposers = heat
Explanation:
this is the best
Answer:
New predators and not a lot of food
Explanation:
If new predators come than they can eat the insects and go extinct. Also if there is not a lot if food than the will die because they have nothing to eat.
Answer:
Cation
Anion
Cation
Cation
Explanation:
If an atom, or atoms, has a balanced number of electrons (negative charge) and protons (positive charge) they are neutral overall. However, if they are not balanced, they will be charged. These charged species are called ions.
What is an anion?
An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them. The number of electrons gained, and so the charge of the ion, is indicated after the chemical symbol, e.g. chlorine (Cl) gains one electron to become Cl-, whilst oxygen (O) gains two electrons to become O2-.
What is a cation?
A cation has more protons than electrons, consequently giving it a net positive charge. For a cation to form, one or more electrons must be lost, typically pulled away by atoms with a stronger affinity for them. The number of electrons lost, and so the charge of the ion, is indicated after the chemical symbol, e.g. silver (Ag) loses one electron to become Ag+, whilst zinc (Zn) loses two electrons to become Zn2+.
