Viscosity
What defines a pure substance?
A pure substance is made of one substance.
What defines a mixture?
A substance made up of 2 or more components.
What is flow rate?
The speed at which the fluid flows.
What is Density?
A force with which a body is pulled towards the earth.
This term viscosity is defined as:
Fluids resistance to flow.
Which one of these is a pure substance: tap water or filtered water?
Filtered water.
Which one of these items is a mixture: Orange Juice or aluminum foil?
Orange Juice
Which liquid would have a faster flow rate: Molasses or Ketchup?
Ketchup
What is volume?
The amount of volume or space occupied by an object.
How do we know which liquid is more viscous than the other?
Based on a fluid's flow rate.
What is filtration?
Filtration is used to separate solids from liquids and gases. When a solution is poured through a filter, solid parts are trapped and the liquid or gas passes through. If the solid is small enough, it may still pass through the filter.
In ________ __________ the different kinds of particles are not mixed evenly.
In a mechanical mixture, the different kinds of particles are not mixed evenly.
What is buyoancy?
The tendency of an object in a fluid to rise or sink due to density differences.
This metric can never be zero.
What is mass.
Why does viscosity differ?
Viscosity is a result of particle flow and internal friction.
This substance is a tool used for cooking... mainly in BBQ.
Aluminum foil
How do particles of a mixture look?
Particles are mixed together evenly.
What term defines why oil floats on water?
Density
This unit of measurement is calculated by dividing Density by volume.
How are viscosity and flow rate related?
The more the flow rate, the less viscous is the fluid (low viscosity) and less the flow rate, the more the viscous is the fluid (high viscosity).
This pure substance is created in your household through a filter or reverse osmosis. (Hint: It makes up most of your body)
Filtered/Distilled Water
This substance is made up of iron, chromium and nickel particles.
Stainless Steel
What would float on water? A Rock or a Wooden Log?
Wooden Log.
Which method states that: move faster and spread farther apart when they are heated?
Particle theory.
