Flashcards in Big Idea 1 And 2 Particle Theory Deck (17):
1

What are the different states of matter

Solid. Particles are tightly packed and only vibrate
Liquid are semi spread out and move flowly.
Gas farther apart and faster

2

What do all fluids demonstrate

The property of viscosity or the internal friction that causes a fluid to resist flowing.

3

What are some different ways to explain particle theory. How does it show particle theory.

-A model of matter - see particles and how they move
The different states of matter - see how they move and can change
What happens when it changes states - ^^

4

Particle theory

- all matter is made up of tiny particles
- diff. Substances are made of different particles
- particles are always moving and or vibrating
- particles move differently in solids, liquids and gasses
- adding heat makes particles move more or vibrate faster. State of matter changes

5

What is a fluid

Any matter that has no fixed shape but it takes the shape of its container. Liquids and gasses are both considered to be fluids

6

What are some examples of hazardous household products(HHPS)

Poisonous (has a skull/octagon/triangle/red)
Flammable(has a flame)
Explosive (something exploding)
Corrosive (x-ray with a hand)

7

What does HHPS stand for

Hazardous household product symbols

8

What does WHMIS stand for

Workplace hazardous materials info systems

9

What is viscosity

Viscosity is the internal resistance or friction in a fluid. This slows it down. The more friction the higher the viscosity

10

How can we test the viscosity in fluids

Ramp method - put it down see how fast it goes
Bubble method - put a bubble at the bottom of a test tube full of a liquid. How fast it gets to the top

11

How does temperature affect viscosity

It does because of how particles move with heat. Faster the particles move the easier it is for other particles to fit and make room. More viscosity

12

What is density

Density is the amount of matter or particles in a given volume

13

How can particle theory help us understand density

The more dense some thing is the more particles it has. The more tightly packed the particles equals more dense

14

The difference between mass and weight in science

Weight - is a measure of force gravity on an object
Mass - the amount of matter in an object

15

If an astronaut traveled to another planet would the asrtonauts mass or weight change.

You are still made up of the same amount of particles, but the amount of weight would change due to gravity

16

What is volume

How much room an object takes up

17

Draw the equation triangle

M
Divide
V Multiply. D

D = m
V
