What does WHMIS stand for?

Workplace hazardous material information system

What is a fluid

A fluid is anything that flows and has no shape can be gas or liquid

What is a slurry

Mixture of liquids and solids, used to transport solids

What is the difference between a mixture and pure substance

A mixture is a bunch of different things mixed together, and a pure substance is only one thing

What is the difference between a homogeneous mixture and a heterogeneous mixture how much genius mixture means there is multiple things inside, but nothing is visible. Hetero genius mixture means that multiple things are inside but stuff is visible

Is Clamato heterogeneous or homogeneous

It is homogeneous

What is the suspension?

A cloudy mixture, That is only together for a short period of time

What's a solute

Solute is something that's being dissolved

What's a solvent

A solvent is something that a solute can be dissolved in

What is concentration?

The concentration of a solution is the amount of solute in a specific amount in a solvent

What affects solubility

Temperature, type of solvent, and type of solute

What are the four points of the particle model of matter

Particles make up everything, they are moving constantly, they are attracted to one another, and there's space in between them

What is viscosity

Scotty is the measure of a fluids resistance to flow

Fluids with a low viscosity means what

They have little internal resistance or friction, or they flows quickly

Fluids with low viscosity means what

They flow slowly and they have a greater amount of internal resistance

What does it mean when a fluid has lots of internal resistance

It means the particles are tightly packed, and it has high viscosity

What does it mean when Fluids has very little or no internal resistance

They have low viscosity, And the particles are looser

Is pancakes syrup more viscous or less viscous

The syrup is more viscous

What happens to more viscous fluid's when they are heated up

They become less viscous because it gets warmer

Does increasing the temperature lowers the Viscosity

Yes

What is density

The amount of matter in a given volume

What does density depend on

Volume and mass

What is the equation for density

Mass times volume

What is the saturation point

It's the point where solvents can't Dissolve any more solute's

Does water become more dense or less dense when it is frozen

It becomes less dense because ice floats on water

What is buoyancy

The tendency of a fluid to float
