Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. If you need more explained ust ask and I an give it more detailed :)
a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
Explanation:
A transverse wave is a wave that the medium is displaced perpendicular to the direction of the wave, such as waves on a string.
A wave is a disturbance that transmits energy from one place to another.
There are two major types of waves:
- Transverse waves are waves that are propagated perpendicularly to the direction of the wave.
- A wave in string going up and down is a transverse wave.
- Electromagnetic waves are transverse waves.
- Seismic s-waves are transverse waves.
- Sound waves are longitudinal waves propagated parallel to their source.

Answer is: reactivity series or activity series.
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity). This series are used to summarize information about the reactions of metals with acids or water, double displacement reactions (more reactive metals displace metals with lower reactivity) and the extraction of metals from their ores.
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.
