What is viscosity?
The viscosity of a fluid is a measure of its resistance to deformation at a given rate, Is the resistance to flow (thickness)
What is Density?
It is the mass of a substance per unit of volume of that substance (how much stuff is crammed into a space)
Diffusion is...
The movement of gas particles from an area of high concentration to an area of low concentration
What is a Fluid?
A moveable liquid
What happens to the pointer? (On a Scale)
If the arrow is pointed to the bottom which means there is no mass, or less than 300 grams of mass on the scale. If its pointing up its the opposite
Viscosity is known as the _________________ of a substance.
Thickness
What is buoyancy?
The upward force by fluids is buoyancy
Describe the motion of the gas particles
the particles move randomly and collide with one another
The 3 states of Fluids are...
Liquid, gas and Plasma
How do you balance the object on the measurement tray?
After placing items on the measurement tray, you move the riders until your arrow is at the zero mark
How does temperature affect viscosity?
The molecules gain energy
Move farther apart
Cohesive force is weaker, decreasing viscosity and increasing the flow rate
What is Mass, Weight and Volume
Mass-Is the amount of matter in a object
Weight-Force of gravity pulling on a object
Volume-Is the amount of space occupied by an object
How does the temperature of the gas relate to the motion of the particles?
The greater the temp is the faster the particles will move around
Ketchup is an example of a ___________Fluid.
Non-Newtonian
What are three objects that are on the retort stand
Clamp,beaker & granulated cylinder
What force is keeping the water molecules around other water molecules?
Cohesive force
What is the equation for density?
Density=Mass divided by volume or D=M/V
When the numbers don’t change much, the particles are said to be in _____________.
dynamic equilibrium
A device used to measure the flow rate of a liquid is known as a...
Viscometer
What are hydraulics and phonemics?
Hydraulics is the mechanical properties and use of liquids.Hydraulics is the liquid counterpart of pneumatics, which concerns gases .Pneumatics is a engineering that uses gas or pressurized air.
How does cohesion affect viscosity?
The particles of the same type of fluid are able to to flow past eachother.
What is the Archimedes principle of buoyancy?
The buoyant force on an object immersed in a fluid is equal to the weight of the fluid displaced.
Smell microwave popcorn? The oddly enticing scent can fill a whole house.How do you think the smell of popcorn spreads through the air?
the scent is carried though the air with tiny organic molecules that are released from the popcorn when heated(The particles go from high concentrations to low concentrations)
Properties of Solid, liquids and gases
Solid-definite shape,mass the same Liquid- definite mass take a shape of container Gas-definite mass fill any space
Why is a graduated cylinder called graduated cylinder?
As its name indicates, it is a glass cylinder with marks along the side similar to those on a measuring cup. ... The volume is read by looking at the top of the fluid from the side and reading the mark on the glass from the lowest portion of the lens-like meniscus of the liquid.
