7.0 Flashcards

some of the stuff isn't on the textbook (even though I tried to add most of it). this is just to memorize the terms.

Fluid

Fluid

Any substance that flows

Examples of fluids

Oxygen, blood, carbon dioxide, lava, oil

Slurry

A mixture of water and solids

Examples of slurries

Cement slurry and paper slurry

Froth flotation

A method used to convert mineral ores to liquids

Hydroseeding

The process of spraying a slurry of seeds, fertilizer, and sawdust in difficult to reach areas

Fluids are easy to ____ and take _____ of their containers

Move, shape

Uses for fluids

Oil: reduce friction in car engine

Paint: prevent formation of rust by creating a barrier

Oxygen: Used in breathing tubes and bicycle pumps

Matter

Anything that has mass and volume

Mass

A measure of how much matter there is in a substance

Volume

A measure of how much space a substance takes up

Particle theory of matter

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 particles move

5. In liquids and solids, the particles are close together and have strong forces of attraction between them

6. In gas, there are spaces between the particles

Thermal expansion

An increase in the volume of a substance in response to an increase in its temperature

Why do liquids flow and take shape of their container?

Because particles in liquids overcome some attraction to each other, and slide past each other

Why do gases flow and spread out to all parts of their container?

Because gas particles move so quickly and are so far apart that they overcome nearly all of their attraction to each other

How does the particle theory explain properties of fluids?

The particle theory explains that particles of a substance, although attracted to each other, can be more attracted to particles of another substance.

Dissolving

When solute particles are more attracted to solvent particles than to each other, causing the solute to disperse within the solvent due to the solvent particles' motion.
