Vocabulary
The degree Canada uses to measure the temperature
Celsius
The state of matter with no definite shape or volume
Gas
The temperature at which a liquid turns into a gas
Boiling Point
When matter heats up, its particles move faster and spread apart, causing the material to take up more space.
Expansion
The equation for density
Density = Mass/volume
The thing that keeps us on the ground
Gravity
The state of matter with a definite shape and volume
Solid
The process of matter changing from one state (solid, liquid, gas) to another
Phase Change
The temperature at which water freezes
0 degrees celcius
The solid that is less dense than water
Ice
Attraction or repulsion that arises between electrically charged particles because of their motion
Magnetic Forces
The state of matter with a definite volume but no definite shape
Liquid
Increasing the temperature of a substance, causing particles to move faster
Heating
When matter cools down, its particles move slower and come closer together, causing the material to take up less space.
Contraction
The relationship between the mass of the substance and how much space it takes up (volume).
Density
A force applied to an object by another body that is not in direct contact with it
Non-Contact Force
The theory of how matter is made up of tiny particles in motion
Particle Model of Matter
The temperature at which a liquid turns into a solid
Freezing Point
The temperature at which ice melts
0 degrees celsius
A tool that measures temperature by the expansion and contraction of a liquid
Thermometer
Forces that pull particles together
Attractive Forces
The states of matter
Decreasing the temperature of a substance, causing particles to move slower
Cooling
The temperature at which water boils
100 degrees celsius
The temperature considered 'room temp'
22 degrees celsius
