Characteristics of Fluids
___________ affects the speed at which particles move
What is Temperature?
This is the increase in volume of a substance in response to an increase in its temperature
What is Thermal Expansion?
The formula to solve for density it ...
What is mass divided by weight?
Maple syrup is thicker than soy sauce so it would flow ______
What is slower?
There are two types of fluid systems. What are they?
What are pneumatic and hydraulic systems?
What is a solid?
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?
Objects that have a lower viscosity will have a ____________________.
What is high flow rate?
This must happen in order for gas to used in a fluid system
What is compressed?
What state of matter has particles moving more freely and is bound less closely
What is gas?
A helium balloon brought outside in the winter will demonstrate what?
What is thermal contraction? The slowing of particles from the cold temperature causes contraction and less pressure against the balloon, making it appear less full.
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?
If a fluid is allowed to move, it will always go from an area of _________ pressure to an area of lower pressure
What is higher?
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?
If the volume of the container cannot increase, but the fluid inside is being heated, this will often result in...
What is an explosion?
Hydraulic systems are very useful for what?
Moving fluids over long distances?
Describe/compare the effect of temperature on the viscosity of liquids and gases
liquids: increase of temperature decreases viscosity
gases: increase of temperature increases viscosity
States that a pressure change in a confined fluid is transmitted equally in all directions throughout the fluid.
What is Pascals Law?
What is the mass of an item that has a density of 0.0013g/mL and a volume of 550 mL?
0.715 g
Why do higher altitudes have less air pressure?
The air in higher altitude levels will be much less dense than closer to the surface?
The definition of a fluid system is...
A fluid system is a group of parts, including at least one fluid, which interacts with each other and function together as a whole.
