This is a Clilstore unit. You can .
In this video we are going to talk about SOLIDS, LIQUIDS and GASES
One thing which is common between SOLID, LIQUD and GASES are PARTICLES.
Imagine PARTICLES as small balls which are always moving. These particles behave differently in SOLID, LIQUID and GASES
Let's talk about Solids first
Some examples of SOLIDS are
What is common in all these Solids?
1. The particles in SOLIDS are very close together and are arranged in a regular pattern
3. They are also held together by strong forces
4. and finally they cannot move from place to place
Now we will talk about LIQUIDS
Some examples of LIQUIDS are
1. The particles in LIQUIDS are not as close together as in solids
2. They are arranged in random way and
3. They are not held as tightly together as in SOLIDS, thus enabling it to move freely.
Lastly we will talk about GASES
Some examples of GASES are
Gases coming out of a car
1, The particles in gas are not close together
2, they are arranged in a random way
3, 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
LIQUIDS like water can flow because
And finally GASES like oxygen can move freely because
The particles are arranged in regular pattern The particles are arranged randomly The Particles are arranged randomly
They are close together They are not as close as in Solids
They are very far apart
And the forces between the particles are very strong
And the Forces between the particles are not as strong as in solids therefore it allows them to flow
And the Forces between the particles are very weak therefore they can spread freely.
