Hello everyone!
In this video we are going to talk about solids,
liquids and gases.
One thing which is common between solids,
liquids and gases are particles.
Imagine particles as small balls which are always moving.
These particles behave differently
in solids, liquids and gases.
Let's talk about solids first,
some examples of solids are
ice cubes, an apple and a car.
What is common in all these solids?
The particles in solids are very close together
are arranged in a regular pattern,
they are also held together by strong forces.
And finally they cannot move from place to place.
Now we will talk about liquids.
Some examples of liquids are
juice, milk and water.
The particles in liquids are not as close together as in solids.
They are arranged in random way
and they are not held as tightly together as in
solids,
thus enabling them to move freely.
Lastly we will talk about gases.
Some examples of gases are
air, oxygen and gases coming out of a car.
The particles in gas are not close together
they are arranged in random way
and forces between the particles are tiny.
And therefore they can move freely wherever they want
So in nutshell,
solids like wood
are hard because
the particles are arranged in a regular pattern.
They are close together
and the forces between the particles are very strong.
Liquids like water can flow because
the particles are arranged randomly.
They are not as close as in solids
and
the forces between the particles are not as strong as in solids
therefore it allows them to flow.
And finally,
gases like oxygen
can move freely
because
the particles are arranged randomly.
They are very far apart
and
the forces between the particles are very weak
therefore they can spread freely.
Thank you for listening.
I hope it was useful.
