|---|---|---|---|---|---|
| Viscosity | Fluids resistance to flow
🗑
|
||||
| Does corn syrup or oil have a higher viscosity? | Corn syrup (thicker) has a high viscosity; oil (thinner) has a low viscosity - flows faster
🗑
|
||||
| What happens to viscosity if you increase temperature of the fluid? | Increasing temperature decreases viscosity because the particles in the fluid move faster and the fluid flows faster
🗑
|
||||
| Buoyancy | Buoyancy is the upward fore that a fluid exerts on an object.
Example: Buoyancy is a rubber duck floating in a tub of water.
🗑
|
||||
| What is the Archimedes’ Principle? | The buoyant force on an object immersed in a fluid is equal to the weight of the fluid that the object displaced.
🗑
|
||||
| Positive Buoyancy | The tendency of an object to float or rise in a fluid because the object weighs less than the fluid it displaces.
🗑
|
||||
| Neutral Buoyancy | The amount of force pulling down (gravity) equals the amount of force pushing up (buoyancy) – an object will remain at constant level in fluid (neither sink nor rise)
🗑
|
||||
| Negative Buoyancy | The tendency of an object to sink in a fluid because the object weighs more than the fluid it displaces.
🗑
|
||||
| Cohesion | The attraction of a particle to one of the same substance
🗑
|
||||
| Adhsion | The attraction of a particle to another particle of a different substance
🗑
|
||||
| Surface Tension | Surface tension is a property of liquids where the exposed surface shrinks to the smallest possible area because of unequal forces near the surface.
🗑
|
||||
| Force | A push or pull that causes movement.
🗑
|
||||
| Flow Rate | How quickly a fluid flows in a given amount of time.
🗑
|
||||
| Dynamic | A term used to describe systems that involve movement such as moving liquids
🗑
|
||||
| Formula to calculate Viscoscity | Viscosity = Mass/Density
🗑
|
||||
| Density | Mass per volume of a substanc
🗑
|
||||
| Formula to calculate density | Density = Mass/Volume
🗑
|
||||
| Mass | Mass is the amount of matter in an object.
🗑
|
||||
| Formula to calculate Mass | Mass = Density X Volume
🗑
|
||||
| Formula to calculate volume | Volume = Mass/Density
🗑
|
||||
| Aerodynamics | The motion of GAS moving around solid objects.
🗑
|
||||
| Example of aerodynamics | Air moving over a car driving down the road
🗑
|
||||
| Hydrodynamics | The motion of LIQUID moving around solid objects
🗑
|
||||
| Example of hydrodynamics | Water moving around a boat travelling through the water
🗑
|
||||
| Kinetic Molecular Theory (4 Parts) |
1. All matter is composed of particles
2. The particles are in constant motion
3. Forces of attraction hold molecules together
4. Adding energy (ie: increase temperature) to a sample of matter will cause the particles to move faster and spread
🗑
|
||||
| Melting | Process of a substance changing from a solid to a liquid (ie: ice melting into water)
🗑
|
||||
| Evaporation | Process of changing a substance from a liquid to a gas (ie: water boiling into steam)
🗑
|
||||
| Condensation | Process of changing a substance from gas to a liquid (ie: moisture on your glasses coming into a warm house after being outside in the cold)
🗑
|
||||
| Solidification | Process of changing a substance from liquid to a solid (ie: water freezing into ice)
🗑
|
||||
| Sublimation | Process of changing directly from a gas to a solid or form a solid to a gas (ie: dry ice creates fog)
🗑
|
||||
| Matter | Anything that has mass and takes up space
🗑
|
||||
| Energy | ability to make things move
🗑
|
||||
| Atom | The smallest unit of matter that maintains the characteristics of an element
🗑
|
||||
| Weight | Weight is the amount of matter an object has with gravitational force
🗑
|
||||
| Formula for calculating weight | Weight = gravitational force X Mass (measured in Newton)
🗑
|
||||
| Formula to calculate flow rate | Volume / Time
(ie: 640 ml: volume, 8 minutes: time = 640/8 = 80 ml per minute)
🗑
