Answer:
Explanation:
There are three states of matter; solid, liquid and gaseous states.
The solid state of matter has it's particles tightly packed with very restricted or no movement within the molecule hence the reason for it's definite shape.
The liquid state of matter has it's particles with a free movement (better than solid but not as free as gases) within the molecule hence it's particles are loosely packed within the molecule. Hence, they (liquids) assume the shape of the container in which they are stored and they move freely when released from the container.
The gaseous state of matter has it's particles totally loosely packed as a result of it's particles moving freely and colliding against one another.
Thus, we can use the above descriptions to answer the statements from the question.
1) The atoms in a ----- are closely packed, but able to slide past each other. Answer: From the description above, it can be deduced that the atoms here are in a solid because the particles within a solid are closely packed.
2) The atoms in a -------- spread as far apart as possible.
Answer: The atoms here are in gaseous form because, as described earlier, they are loosely packed and can thus be as far apart as possible.
3) A ----- has a definite shape and volume.
Answer: As described earlier, a solid substance would have a definite shape and volume because it's particles are tightly packed.
4) The shape of a ----- can change, but the volume is definite.
Answer: The substance here is a liquid because the particles are free (but not as free as gases) and would have a definite volume but will assume the shape of the any container they are placed in (hence they have an irregular shape).
