A fluid is any liquid that flows
Which of the following IS NOT a purpose of liquids
Transport solids
Become Solids
Hold other materials
Expand Solids
A slurry is a mixture of:
Solids and Gases
Solids and Liquids
Solids and Plasma
The Particle Theory describes matter and its behavior
When objects heat up, they gain forces of attraction and spread apart
The formula for density is:
Density=Mass/Volume
Density=Force/Area
Density=Force x Distance
The main point of the ball and ring experiment was to prove that global warming is having a major effect on our everyday lives
Viscosity:
Describes how dense a fluid is
Is a fluid's resistance to flow
Measures the speed at which a fluid flows from one point to another
Density is the amount of mass contained in a given volume
Archimedes Principle states that when force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid
Fish have a swim bladder that enables them to fill their system with carbon dioxide and increase their density
The formula for pressure is: force/area
Compression is:
An increase in volume caused by force
A decrease in volume caused by force
A hydraulic system is a system that uses a liquid under pressure to transmit a force to do work
A mechanism is
A group of physical parts that interact with one another
Any device that helps us to work
A machine that requires the application of a single force to do work
Several different types of machines that work together to perform a specific function
Weight is the amount of matter in an object
Work is done
When a force causes an object to move a distance
When a machine changes the direction of a force
Energy is the ability to do work
Energy is measured in
Joules
Meters
Pascal's
Centimeters
Energy can be created but not destroyed
Friction
Is a force that opposes motion
Is not calculated in IMA
Does not always exist in machines
The input force is the force that the machine applies to the object or the force required to move the object
Which of the following is not one of the simple machines?
Wheel and Axel
Screw
Lever
Bicycle
Screwdriver

Aquifer
Water Table
Which of the following is not a main watershed?
Hudson's Bay
Caribbean
The Dead Sea
Gulf of Mexico
Pacific
Vancouver has a more regulated climate than Winnipeg
Water has a high heat capacity
When glaciers decrease in size sea levels would lower
A septic tank is commonly found in
Rural Areas
Urban Areas
The green method of filtering water is the waste water treatment plant
