CHEMISTRY FINAL TEST - Matter & Particles Chapter 1

What are the 4 states of matter?

What are the 4 states of matter?

Solid, Liquid, Gas & Diffusion

What is diffusion?

Diffusion is the fast movement of particles from high concentration to low concentration.

What is the smallest single particle?

Atom

Sometimes particles can be made up of more than one atom, what is that substance then called?

Molecules

Sometimes, atoms are groups of atoms carry a charge, what is it called?

Ion

What is the structure of solid?

They have a fixed shape, fixed volume and do not flow.

What is the structure of liquid?

They have a fixed volume, they flow easily and takes the shape of it’s container

What is the structure of gas?

They have no fixed shape or volume and takes the shape of it’s container

Solid → Liquid . What is this conversion called?

Melting

Solid → Gas . What is this conversion called?

Sublimation

Liquid → Solid . What is this conversion called?

Freezing

Liquid → Gas . What is this conversion called?

Evaporation

Gas → Solid . What is this conversion called?

Deposition

Gas → Liquid . What is this conversion called?

Condensation

What’s the boiling point of water?

100°C

What’s the freezing point of water?

0°C

What’s the particle arrangement like for solids?

Particles are close together in lattice, the particles cannot move and only make vibrations.

What’s the particle arrangement like for liquids?

Particles are close together but not as tight as solids, particles can move about.

What’s the particle arrangement like for gas?

Particles are far apart and move very quickly.

Big Hint (Flip Card)

haha get rickrolled again

What happens to the particles when it’s melting?

There will be vibrations that gets larger until it expands to a liquid.

What happens to the particles when it’s boiling?

The particles will move faster until it gets enough energy to escape.

Label Parts: A B C

A = Solid
B = Liquid
C = Gas

Label Parts: A B C

A = Solid
B = Liquid
C = Gas

In a gas, what happens if the pressure is increase or decreased?

If increased, volume is decreased. If decreased, volume increases.

In a gas, what happens if the mass of the particles are lower?

It will diffuse faster.
