An increase in thermal energy, changes the state of matter from solid to liquid to gas.
The particle diagram that represents a mixture of three substances is seen in Option 2.
A particle is a small portion of a matter that has both physical and chemical properties.
In inorganic chemistry, a substance refers to a form of matter ( usually particles) that can not be separated by ordinary physical means but by a chemical process.
It can either be:
- an element or a compound.
From the information given, we have:
- an atom of one element
- an atom of a different element
Option 1, 3, and 4 show a particle diagram representing a mixture of only two substances but Only Option 2 shows a particle diagram representing a mixture of three substances.
Therefore, we can conclude that the particle diagram that represents a mixture of three substances is seen in Option 2.

The liquid that is use to dissolve solute
Answer:
1. Removing them to an area of fresh air. This helps to prevents further poisoning by the carbon monoxide and increase the amount of oxygen entering into the body. This will help to reduce the concentration of carbon monoxide binding oxygen
2. Administering pure oxygen goes a long way to enhance ventilation and increase the oxygen saturation to 100%. This will help to overcome the effect of the carbon monoxide and promote more hemoglobin binding
