States of Matter
What are the 3 states of matter?
Solid, Liquid, Gas
Burning wood
Chemical
Solid to a liquid
Melting
Define matter
Anything that has mass and takes up space.
Name 2 properties of solids
1. Particles are tightly packed together
2. Particles cannot move past each other
3. Do not flow
4. Does not take the shape of its container
Making paper
Chemical
Water from a boiling pot of water turning into vapour
Evaporation
What are some indicators of a chemical change?
Smell
Appearance (Colour)
Build up on the surface (rust)
The production of gas
Name 3 properties of liquids
1. Particles have SOME space between them
2. Particles can move past each other
3. Can flow
4. Takes the shape of the container it is in
Baking a cake
Chemical
Gas to a liquid
Condensation
Physical change
A change in the state of matter, it can be reversed, no new substance is formed
Name 3 properties of gases
1. Particles are far apart
2. Particles can move freely past each other
3. Can flow
4. Takes the shape of the container it is in
Melting chocolate chips
Physical
A puddle drying up throughout the day
Evaporation
Chemical change
A chemical reaction, it cannot be reversed, a new substance is formed
What is oobleck an example of?
A non-newtonian fluid
The condensing of water vapour
Physical
Water vapour hits a cold surface
Condensation
Compare a physical change vs a chemical change and give an example of each
Physical change - a reversible change, a change in the state of matter. Ex: ice cube melting
Chemical change - a result of a chemical reaction, a new substance is formed, and is irreversible. Ex: boiling an egg
