Big Idea 1 And 2 Particle Theory Flashcards
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
What do all fluids demonstrate
The property of viscosity or the internal friction that causes a fluid to resist flowing.
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 - ^^
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
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
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)
What does HHPS stand for
Hazardous household product symbols
What does WHMIS stand for
Workplace hazardous materials info systems
What is viscosity
Viscosity is the internal resistance or friction in a fluid. This slows it down. The more friction the higher the viscosity
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
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
What is density
Density is the amount of matter or particles in a given volume
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
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
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
