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.

Answer:
The correct answer will be "
".
Explanation:
We have:
Moles of solute (Na₂Co₃) = 
= 
= 
Now,
The volume of the solution will be:
⇒ 
∴ 
The formula to find the concentration will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
The answer is:
- metalloids are semiconductive.
- metalloids are amphoteric.
The explanation:
The metalloids are only 6 elements in the periodic table which are boron, silicon, germanium, arsenic, antimony, and tellurium. And its properties are intermediate between the nonmetal and the metal. and their properties are brittle, shiny ,solid. but the properties that are unique to metalloids.
