Answer:
Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.
A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.
Explanation:
Solids have <u>a fixed volume and shape</u>. They also vibrate in a fixed position. Ice
Liquids have <u>do not have a fixed shape but a definite volume</u>. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water
Gases <u>do not have a fixed shape or volume</u>. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour

Answer:
If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.
Explanation:
Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.
If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:
ρ = m/V
Therefore, according to the mass and volume of the rock
ρ = 12 grs / 2 cm³
<em>ρ = 6 grs/cm³
</em>
Being the density of the rock equal to 6 gr/cm³.
Answer:
VESICLES
Explanation:
Molecules of different types are produced in different compartments of a cell. These molecules, however, needs to be transported from one location to another. For this purpose, small spherical structures called VESICLES are used by the cell.
Vesicles are compartments in the cell that functions majorly as transport sacs. They help transport materials and molecules from one organnelle to another within a cell. For example, transport vesicles help in the transportation of matured proteins from the Golgi apparatus to respective locations in the cell.
