What are the 4 states of matter?

Solid, Liquid, Gas, Plasma

100

Who first proposed the particle model of matter?

John Dalton

100

What is Viscosity?

The thickness of a liquid

100

What is kinetic energy?

Movement energy

100

Who first came up with the idea of atoms?

Democritus

200
What is the process called where a solid changes to a liquid?

melting

200

When particles are lined up in a regular arrangement and held close together, they are in what state of matter?

Solid

200

What are the two types of strength?

Tensile and compressional

200

If we add heat to a substance, what are we adding?

Kinetic energy. 

200

All matter has what two things?

Mass and Volume
300

When a gas changes to a liquid, it is called . . .

condensation

300

When particles are far apart and move quickly on their own, they are in what state of matter?

Gas

300

What is density?

The amount of mass per volume

300

What happens to particles when we add heat?

They move faster as they have more kinetic energy.

300

What is diffusion? Give an example.

The movement of something with high concentration into an area of lower concentration.

Tea bag in water, perfume, etc. 

400

What are the processes by which a liquid turns to a solid, or to a gas?

solidification (freezing), and evaporation

400

Draw the particles in all 3 states of matter according to the Particle Model

400

A very hard substance will ____________ easily, and is called ______________.

Break; brittle.

400

Heat causes substances to _________. When their temperature decreases, the substance ____________.

Expand; contract

400

Explain the difference between tensile strength and compressional strength

Tensile strength is a measure of the flexibility of the bonds between particles. Compressional strength is the ability to withstand large forces. 

500

What is the process where a solid turns directly into a gas?

Sublimation

500

What is wrong with this representation of the Particle model?

The liquid particles are shown with space between them, but liquids cannot be compressed because their is no space between the particles. They should also not be lined up in order as in liquids the particles move around each other. 

500

What is compressibility? Which states of matter can be compressed and which cannot? 

The ability of a substance to be squashed or compressed.

Gas can be compressed; Solids and liquids cannot be compressed. 

500

What are expansion joints for?

To allow for substances to expand and contract with the addition and decrease of temperature

500

List 5 things we know about atoms

They cannot be divided

We cannot create or destroy them

Atoms have mass

They are too small to be seen

They are always moving

There are spaces between particles

Different atoms combine to form compounds

Etc
