The quantity of matter that a substance or object contains
What is mass
100
When an object expands due to being heated
What is thermal expansion
100
Changing state from a solid form to a liquid form
What is melting
100
The mass of a given volume is...
What is density
100
To find density you must know this formula
What is Mass divided by volume
200
The amount of space taken up by an object or substance
What is volume
200
When an object or substance shrinks in volume due to decreasing temperature
What is thermal contraction
200
Changing state from a liquid form to a gas
What is evaporation
200
The key to density is the spacing of the ...
What are particles
200

Ethyl alcohol will float on oil
300
The Particle Model states 4 laws
What is
1) All matter is made up of small particle
2) There are spaces between the particles
3) Particles are always moving
4) Particles are attracted to each other
300
This device uses red coloured liquid and thermal expansion and contraction in a narrow tube
What is a thermometer
300
Change of state from a liquid to a solid
What is solidification
300
A substance will change it's density and turn from a solid to a liquid because of this
What is heat
300
Mass is measured in this unit
What are grams
400
Energy makes particles move is a part of this theory
What is the Kinetic Molecular Theory
400
Energy transfered from one object to another as a result of a difference in temperature.
What is heat
400
Change of state form a solid form to a gas form
What is sublimation
400
One of these is denser than the other: water/ice
What is water
400
Density of fluids is measured in
Grams per millilitre
500
This type of matter has particles which are close together but can slip by each other
What is water
500
The average kinetic energy of an object's particles
What is temperature
500
The opposite of sublimation
What is deposition
500
When heated a substance becomes less dense/more dense
