Characteristics of Fluids
___________ affects the speed at which particles move.
What is Temperature?
This term is a measure of how much matter is packed within a given volume.
What is density?
The formula to solve for density it ...
What is mass divided by volume?
The density of water is roughly 1 gram per milliletre. An object has a density of 3.6g/ml and when you put it into water, it ______.
What is "sinks"?
There are two types of fluid systems. What are they?
What are pneumatic and hydraulic systems?
This state of matter has a definite shape and volume.
What is a solid?
Anything that has mass and volume.
What is matter?
Since particles of a solid are usually closer together than the particles of a liquid, solids are often ________ than liquids?
What is denser?
Davey has a paperclip that has a mass of 9 g and a volume of 3 cubic centimetres. It has a density of _____.
What is 3 g/cubic cm.
This must happen in order for gas to used in a fluid system
What is compressed?
This state of matter has particles that move more freely and are bound less closely.
What is a liquid?
This happens to water when you submerge yourself in a bathtub.
What is displacement?
The spaces between gas particles are larger than those in solids and liquids, which means that there are considerably fewer particles in a given volume of gas. Gases are much ______ than liquids and solids.
What is less dense?
A graduated cylinder has 20 ml of water. When a marble is dropped inside, the water level increases to 30 ml. The volume of the marble must be ________.
What is 10 ml?
What are some advantages of pneumatic systems.
What is cost efficient, safe, and works well in a range of temperatures?
Fluids such as gases and liquids are able to this...
Hint: Think of moving
What is flow?
This is the upward force that a fluid exerts on an object. It determines whether an object sinks or floats
What is Buoyancy?
If the density of a substance is less than the density of the fluid, the substance will _____
What is float?
This is the formula for calculating mass given an objects density and volume.
what is "m = dv"?
Hydraulic systems are very useful for what?
Moving fluids over long distances?
Objects that have a lower viscosity will have a ______.
What is a high flow rate?
What is Pascal's Law?
A substance generally has a greater density in its solid state than in its __________ and _______ state
What is liquid and gas?
What is a hydraulic system.
