TOPIC 4 Flashcards
what is a fluid
- is anything that can flow
what are the three key points of the particle theory model
- all matter is made up of tiny particles.
- the particles must move freely past one another
what makes a liquid viscous?
if it is thicker than others.
what is viscosity
is a liquids thickness, or the resistance to flow.
flow rate if s measure of what?
liquids viscosity
what is flow rate
the volume of a fluid that passes a point in a pipe or tube in a certain amount of time
the flow rate of a liquid is measured in what
ml/s (milliliters per second)
by measuring the flow rate we are able to comare the….?
viscosity of different fluids.
what will happen if the fluid is thicker
the slower it will flow and the more viscous it is.
does temperture affect the viscosity of a fluid
yes
what happens when you increase the temperature of a fluid
it will lower its viscosity
lowering the temperture of a fluid will
increase its viscosity
what are some things that viscosity is used for
- Motor Oil
- pipelines
- extraction
- cleaning
- cooking
why is motor oil an example of viscosity
because it is a lubricant in engines at different temperatures.
true or false Temperture has the opposite effect on the viscosity of gases as on liquids.
true
