The viscosity of gas——-as it is heated.
Increases
Gases flow more—–than liquids.
Easily
The viscosity of liquids—–as they are heated
Decreases
Buoyant force is measured in…
Newtons
Swim bladders on submarines are called…
Ballast Tank’s
Definition: Viscosity
The thickness or thinness of a fluid.
Definition:Viscous
High viscosity
Definition: lubricant
Used for minimizing friction.
Definition:Flow rate
How fast something flows
Definition:Density
The amount of mass in a certain volume
Definition:Mass
The amount of matter in a substance
Definition:Volume
The amount of space occupied by a substance.
Definition:Weight
The force of gravity exerted on a mass.
Definition:Force
Anything that causes a change in the motion of an object.
Definition:Gravity
The attractive force between masses, causes objects to be attracted to earth.
Definition:Buoyancy
The tendency to rise or float on a liquid
Definition:Buoyant force
The upward force exerted on objects submerged in or floating on a fluid.
Definition:Floating
Remaining suspended in a fluid
Definition:Average density
Mass divided by Volume(Swim bladder)
Definition:Neutral Bupyancy
Gravity=Buoyant force, when they are equal.
Definition:Archimedes Principle
Objects submerged in water displace water
Another way to define viscosity is the…
Resistance to flow.
