Force per square meter
Unit for pressure
Any change in pressure applied at any point on a confined fluid is transmitted undiminished throughout the fluid
A technology that uses Pascal's Principle to compress a fluid which amplifies a force
(Blank) Force is the upward force exerted on an object submerged in a fluid
this principle states that the buoyant force exerted on an object submerged in water is equal to the weight of the water displaced.
This principle states, as the velocity of a fluid increases the pressure it exerts decreases
Bernoulli's Principle helps us explain how (blank) works.
Archimedes' Principle helps us explain how (blank) float.
these forces exist between like substances. "co-workers"
these forces exist between two unlike substances. "Adding two things together"
the result of cohesive forces and make a fluid contract to its smallest possible area.
occurs when a narrow glass tube is placed in a fluid and that fluid moves up the tube. Due to adhesion.
Thermal (blank) occurs when a substance is exposed to various temperatures.
a (blank) has no definite shape and can flow
(blank) pressure exists when air is moving from the ground up. This causes rainny weather.
(blank) pressure exists when air is moving from high altitudes down toward the ground. This results in fair weather.
winds are the result in differences between air (blank).
The concave bend when water is placed in a graduated cylindar. Due to adhesive forces between the cylidar and the water.
A conductive gas-like state of matter consisting of a mixture of free electrons and atoms that are stripped of their electrons.
(blank) expansion occurs when an object changes its length due to a change in temperature
(blank) expansion occurs when a fluid changes due to change in temperature
Coefficient of linear expansion
a constant that tells how a specific material's length changes as the temperature changes
Coefficient of volume expansion
A constant that tells how much the volume of a material will change as the temperature changes
