Analyze the diagram showing the changing states of matter. Drag the item from the item bank to its corresponding match.
iVinArrow [24]

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.

Western regions Facts
babunello [35]
This region has both the state with the smallest population (Wyoming) and the largest population (California).
Alaska's land area is much bigger than any other state, but it has one of the lowest populations.
The western US takes up about half of the land of the United States.

The western United States is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier.


Hope this helps :)

Which equation represents a conservation of atoms?
weqwewe [10]

Answer:

4) 4Fe + 3O₂ → 2Fe₂O₃

Explanation:

4Fe + 3O₂ → 2Fe₂O₃

In this equation the numbers of atoms are same in both side. There are four iron and six oxygen atoms are present on left and right side of equation. That's why atoms are conserved. This equation completely followed the law of conservation of mass.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
