what is buoyancy
the ability or tendency to float in water or air or some other fluid.
what is viscosity
a measure of a fluid's resistance to flow.
what is the particle theory
a simply way of describing matter and its behavior
what is density
how compact or concentrated something is.
what dose the Buoyant force depends on
the density of the liquid
dose viscosity increase with hot temperature
true or false
false
Do particles move faster when heated?
what is the definition of mass
the measure of the amount of matter in a body.
What is Archimedes’ principle?
the buoyant force of an object is equal to the weight of the fluid displaced by the object
The viscosity of liquid
Decreases with increase in temperature
Why are particles attracted to each other
What is the definition of volume?
the measure of the capacity that an object holds
list the factors on which buoyant force depends.
Name a fluid that is viscous
- Maple syrup
- Molasses
Why is the particle theory of matter important?
Why do we need density?
it allows us to determine what substances will float and what substances will sink when placed in a liquid
Which scientist gave an estimate of the buoyant force acting on a solid object using liquid.
Archimedes
what are the three things that determine the viscosity
- Fluid Temperature
- Flow Conditions
- Pressure
say all 6 in order
- All matter is made up of tiny particles
-All particles are in constant motion
- All particles of one substance are identical
- Temperature affects the speed at which particles move
- In liquids and solids, the particles are close together and have strong forces of attraction between them
- In a gas, there are spaces between the particles
