Viscosity Flashcards
What is the particle theory of matter? (five main points)
- All matter is made up of very small particles
- All particles in a pure substance are the same but are different from a different substance
- There is space between particles
- The particles are always moving. They move faster if they gain energy
- There are attractive forces between the particles. Some strong; some weak.
What is viscosity?
-Viscosity is a measure of liquids resistance to flow
What is a fluid? (two points)
-Any form of matter that flows
-The states of matter that can be considered fluids are liquid and gases
What is the flow rate?
the flow rate is the speed when a fluid flows from one point to another
high temperature = ______ viscous
high temperature = less viscous
high concentration = ______ viscous
high concentration = more viscous
high attractive forces = _______ viscous
high attractive forces = more viscous
high particle size = _______ viscous
high particle size = more viscous
What are the three states of matter?
solid, liquid, and gas.
A solids shape is ______
A solids volume is ______
A solids particle arrangement is ______
A solids particle movement is ______
A solids shape is definite
A solids volume is definite
A solids particle arrangement is close
A solids particle movement vibrates
A liquids shape is ______
A liquids volume is ______
A liquids particle arrangement is ______
A liquids particle movement is ______
A liquids shape is indefinite
A liquids volume is definite
A liquids particle arrangement is close
A liquids particle movement is free flowing
A gases shape is ______
A gases volume is ______
A gases particle arrangement ______
A gases particle movement is ______
A gases shape is indefinite
A gases volume is indefinite
A gases particle arrangement is far apart
A gases particle movement is random
What does viscosity determine
Viscosity determines the thickness or thinness of a liquid
How is a fluid that is viscous described?
it is described as “not runny” or thick
what is friction in a liquid?
A force that resists movement
