We measure volume of a liquid with these units and volume of a solid with these units.
What are:
Liquids: milliliters (mL) or liters (L)
Solids: cubic milliliters (mm3), cubic centimeters (cm3) or cubic meters (m3)
100
The definition of mass is this.
What is: The amount of matter in an object.
200
Heating matter causes it to do this.
What is expand?
200
Disolving sugar in water is an example of this form of change.
What is physical change?

What is 24 mL?
200
The definition of weight is this.
What is: The amount of matter in an object plus the amount of gravity that is pulling the object.
300
This state of matter takes the shape of it's container and the volume can change.
What is a gas?
300
The definition of a physical change.
What is: A change in a substance's physical properties (shape, size, volume or mass)
300
We use this formula to measure the volume of a solid.
What is: length x width x height
300
True or false: Weight is constant.
False - weight is not constant, it is dependant on the gravity pulling matter down.
400
Removing energy from water turn it into this.
What is ice? (Freezing)
400
The definition of a chemical change.
What is: A chemical reaction where a new substance is formed.

Mass is measured in these units.
What are: grams (g), milligrams (mg), kilograms (kg) and in some countries - pounds (lbs)
500
In this state of matter, the particles move but the volume does not change.
What is a liquid?

List the 5 ways we can observe a chemical change.
What are:
1. formation of a solid
2. colour change
3. formation of a gas
4. temperature change
5. non-reversable

These are the steps to finding the volume of an irregular object.
The name of this process is _____________.
1. Fill a graduated cylinder with water and measure the volume.
2. Place the irregular solid in the cylinder and observe the change in volume.
What is liquid displacement?
