This rain has a pH less than 5.
What is acid rain?
The density of this substance: has a mass of 36 g and a volume of 10 ml.
What is 3.6 g/ml?
The particles are close together. Has a defined shape and volume.
What is a solid state?
Going from gas to liquid. Also called liquification
What is condensation?
A measure of how much matter is in a substance. It does not change from place to place.
What is mass?
Temperature is measured in this unit.
What is Celsius?

What is 10 g/ml?
The particles are less strongly linked. Has a defined volume but not a defined shape.
What is a liquid state?
From a solid state to a gaseous state
What is sublimation?
The strength with which one object (like Earth or the Moon) attracts another object (like an astronaut).
What is weight?
When the volume of a solid, liquid or gas increases because of a rise in temperature. The particles take up more space as they become agitated.
What is thermal expansion?
Hot air balloons and thermometers work because of this property,
What is thermal expansion?
2.5 MYA humans started making tools out of stone.
What was the Stone Age?
It takes up the entire volume of the container it is in. The particles are not linked, very disorganized. The particles are far away from each other.
What is a gaseous state?
From a gas to a solid. Frost forming on windows!
