What is the definition of Particle Theory?
A simple way of describing matter and its behavior
What did he use to determine the volume of the kings crown?

What is the definition of mass?
A measure of how much matter is in a substance.
True or false; Buoyant force is the downward force exterted by a fluid.

b.) Matter is made up of tiny particles.
True or false; Archimedes lived in Syracuse.
True! He lived in Syracuse in the third century B.C.
What is the definition of density?
Density is the amount of mass in a given volume.
What are 5 examples of buoyancy in daily life.
(Name 5 examples)
What is the word for a solid turning into a liquid?
Freezing is the word for a solid turning into a liquid.
True or false; Heat makes particles move faster
With an increase in temperature, the particles gain kinetic energy and move faster.
What does Arcimedes' principle state?
What is the definition of volume?
Volume is a measure of how much space a substance takes up.
What is the definition of buoyancy?
Buoyancy is the tendancy of an object in a fluid to rise or sink.
What is the state for solid turning into a gas?
Sublimation is the state of a solid turning into a gas.
What are the 6 points about Particle Theory
1. All matter is made up of tiny particles. 2. All particles are in constant motion. 3. All particles of one substance are identical. 4. Temperature affects the speed at which the particles move. 5. In liquids and solids, the particles are close together. 6. In gas there are spaces between.
What did Archimedes yell when he found out about his discovery?
"Eureka!"
A block of wood has a volume of 598cm and a mass of 9458cm. What is the density?
15.8cm
What does buoyancy depend on?
Buoyancy depends on volume and so an object's buoyancy reduces if it is compressed and increases if it expands.
What is the fourth state of matter?
Plasma is the fourth state of matter.
