C1.1/2 - The Particle Model and States of Matter Flashcards
Can you compress a solid?
No
What is a substance?
Something that is made from just one type of particle e.g. gold is a substance made from gold particles.
Does a solid have a ‘fixed shape’?
YES
Can you see the particles that make up materials?
No - they are too small to see.
Can you compress a gas?
Yes - because its particles are far apart
What is meant by the properties of a material?
The features of the material e.g. is it strong
Identify the 3 states of matter.
Solid
Liquid
Gas
Does a liquid have a fixed shape?
No - liquids can take the shape of the container that they are poured into.
Does a liquid flow? (can it be poured?)
Yes- because its particles can roll around each other.
Describe the particles in a solid.
Neatly arranged
Vibrating
All touching
What is a mixture?
A mixture is something that is made from lots of different types of particles e.g. air is a mixture of different particles.
Which state is shown below?
Liquid
Does a gas flow? (can it be poured?)
Yes - because gas particles are free to move around
Which state is shown below?
Gas
Does a gas have a fixed shape?
No - they can take the shape of the container that they are in e.g. a balloon
Does a solid flow? (can it be poured?)
No
What is matter?
The ‘stuff’ that everything is made from.
We say that all materials are made from tiny pieces called…
particles
Describe the particles in a liquid.
Randomly arranged
Rolling around one another
Touching
Which state is shown below?
Solid
Describe the particles in a gas.
Randomly arranged
Moving around
Not touching
Can you compress a liquid?
No - its particles are too close together.
What is meant by a state?
Whether something is a solid, liquid or gas.
