Matter is madeof atoms and molecules.
Water, forexample is the H2O molecule.
This means that a molecules of water has 3 atoms.
A water moleculehas 2 Hydrogen atoms and 1 oxygen atom.
Substances likesugar, have many atoms in their molecules.
A molecule ofsugar has many atoms including carbon, hydrogen and oxygen.
Matter is madeof molecules such as H20, which is the water molecule.
Matter can be inone of three states, solid, liquid or gas.
Water and iceare the same substance but they are in different states.
These statesdepend on the temperature of themolecules.
When we heat a substance,the molecules move faster and try to take up more space. When we cool asubstance, the molecules move more slowly.
When we cool asubstance to its freezing point, it becomes a solid.
In a solid, themolecules move very little. Their positions are almost fixed.
To be fixedmeans that their positions don’t change.
if we heat themolecules, they move faster and away from each other.
The solid beginsto melt like ice cream on a hot day.
At a certaintemperature, a solid begins to change into liquid.
The temperatureat which a solidchange into liquiddepends on the substance. For water, the solid begins to changes into a liquid
when itstemperature rises to above 0 degrees Celsius.
For some
substances, such as steel, the temperature which it becomes a liquid is much
higher. Steel often melts at around 1370℃.
If we continueto heat a liquid, the molecules move even faster.
At a certaintemperature, the liquid begins to change into a gas.
For water, theliquid begins to change into a gas at 100 degrees Celsius.
This is theboiling point of water.
Inside a star,such as our sun, the temperature is very high.
Everythinginside the sun is a gas.
According to scientists,there are over 65 elements inside the sun.
these includeoxygen and iron. Over 90% of the sun is hydrogen gas.
