What is
Amontons's law

400
The process of mixing molecules of one substance with another substance by random molecular motion.
What is
diffusion
?
400
The resistance of a material to certain types of small deformations.
What is
hardness
?
400
States that if pressure is applied to a fluid inside a closed container, the pressure increase will be distributed equally throughout the container.
What is
Pascal's Principle
?
400
A structure that changes the flow of air to produce a force.
What is an
airfoil
?
400
States that the buoyant force experienced by an object is exactly equal to the weight of the fluid displaced.
What is
Archimedes' principle
of buoyancy?
500
Allowing some substances to diffuse through them, but not other substances.

?
500
A technique designed to reduce drag.
What is
streamlining
?
500
States that lateral (sideward) pressure exerted by a moving fluid decreases as the fluid's speed increases.
