What state of matter has no definite shape or volume?
Gasses
What does Soluble mean?
That something can be dissolved in a solvent
How is flow rate measured?
M^3/s
What is buoyancy?
The tendency for materials to rise or float on a fluid.
What is Fluid pressure?
Pressure exerted on a fluid.
What is a fluid?
Liquids or gasses; Matter that flows
What is a Heterogeneous mixture? Give an example
A mixture that looks like two or more substances
What is the formula for density and how is it measured?
Density = Mass/Volume
Grams/cm^2
Whose Principle defines buoyancy?
Archimedes
N/m^2 are also known as?
Pascals
What is the fourth state of matter, excluding solid, liquid and gas?
Plasma
What is a suspended solution?
A solution where the particles are suspended.
What is the difference between mass and weight?
Mass is the amount of matter in an object and Weight is the amount of Gravity pushing it down.
When an object is buoyant it...
Pushes against Gravity
What is a Hydraulic system?
A closed system using force exerted on a liquid to do work.
What is it called when a gas turns straight into a solid and vice versa?
Sublimation
What is a compound?
A pure substance with two types of atoms
If you heat a liquid will its flow rate go up or down?
Down. It will become faster.
"The buoyant force acting on an object is equal to the amount of fluid displaced by an object." What is this?
Archimedes Principle
Kilo pascals are equal to how many pascals?
1000
What point did we add to the particle model of matter this year?
When you heat particles they speed up and when you cool particles they slow down.
What do Under saturated, Saturated, and Super saturated relate to?
How much solute is dissolved in a solvent and how much solute a solvent can have dissolved at a certain tempurature
If you cool a gas will its flow rate go up or down?
Down. It will become faster.
What is Average density? Use a real world example.
Average density is the total mass of an object divided by the total volume. Example: Boats use this to float.
What is pressure?
The force exerted perpendicular to an object/ the area of the surface on which the force adds. Or, Force/Area.
