Ex. Lemonade powder is mixed into water. This is an example of a solid mixed into a liquid or liquid mixed with a liquid?
A mixture is 2 substances that can be easily _____
separated
A solution is a type of __________________
mixture
All matter is made of ________________
What are properties?
Characteristics of matter.
List 3 properties of glass.
clear
strong
solid
Give an example of a mixture
Give an example of a solution
Example: salt water
All matter is made of particles too small to be _________
seen.
Give an example of an emulsion.
Ketchup, salad dressing, paint, oil and water
Define homogeneous
1 set of properties.
Looks the same throughout (uniform).
What are the two types of mixtures?
Homogenous and heterogenous
How are solutions and mechanical mixtures similar?
They both have 2 substances mixed together.
Three states of matter
What is solid, liquid, and gas?
What is suspension?
When 1 substance is suspended (floating) in another substance.
List the 2 points of the particle theory.
All matter is made up of extremely tiny particles.
Each pure substance has it's own type of particle different from another pure substance.
True or false?
All solutions are mixtures, but not all mixtures are solutions
True
True or false?
Some mixtures are solutions and some solutions are mixtures.
False
List the 2 points of the particle theory.
All matter is made up of extremely tiny particles.
Each pure substance has it's own type of particle different from another pure substance.
What is mass?
The total amount of matter that makes up something.
I mixed an orange substance with water. I put it by the window and left it there for 2 days. The sun was shining brightly those 2 days. I come back and there is only an orange substance left at the bottom of the container. Where is the water?
Evaporated. Different rates of evaporation means that the water evaporates quicker than the orange substance.
What is an example of a heterogenous mixture? (heterogeneous mixtures have substances that keep their properties)
Examples: cereal, trail mix, salt and sand
When I mix food colouring into water, during what point is the mixture heterogeneous?
At the beginning before it is evenly mixed and before the particles distribute themselves evenly.
1. In which state(s) of matter does the material have definite shape and volume?
2. In which state of matter can the particles move very freely and it takes the shape of its container?
1. Solid and liquid.
2. Gas
Explain malleability and viscosity.
Malleability: The ability of a substance to be rolled or hammered into thin sheets.
Viscosity: A measure of the resistance of a liquid to flow.
