The correct matches for changes of state are:
- 1 or 3 : Arrow that shows particles getting closer together
- gas: State of matter that would fill any container
- liquid: State of matter with definite volume but NOT shape
- 2 or 4: Arrow that shows particles gaining energy
- solid: State of matter with definite shape
<h3>What is change of state?</h3>
Change of state is the process whereby matter in one physical state is converted to matter in another state by the addition or removal of heat.
The process of change of state are:
- Melting: solid to liquid due to addition of heat
- Vaporization: liquid to gas due to addition of heat
- Sublimation: solid to gas due to addition of heat
- Freezing: liquid to solid due to removal of heat
- Condensation: gas to liquid due to removal of heat
- Deposition: gas to solid due to removal of heat
Considering the given diagram, the correct matches are:
- 1 or 3 : Arrow that shows particles getting closer together
- gas: State of matter that would fill any container
- liquid: State of matter with definite volume but NOT shape
- 2 or 4: Arrow that shows particles gaining energy
- solid: State of matter with definite shape
In conclusion, change of state of matter occurs due to heat changes.

It would be the needle pressure gage temp check
To get a result with the best degree of precision, the
number of significant figures should be equal to the smallest number of
significant figures of the given numbers. In this case, the smallest is 3 as
given by the number 9.03 mL.
Therefore density is:
<span>11.50 g / 9.03 mL = 1.27 g/mL</span>
Answer:
Macromolecule: polymer
Repeating units: monomer
Simple molecule: monomer
Covalent bonds: both
Explanation:
A macromolecule is a very large molecule commonly created by the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more.
A monomer is a molecule that can be reacted together with other monomer molecules to form a larger polymer chain.
Polymers include bounds between nonmetal atoms, therefore, they are joint by covalent bonds
