Introduction to Thermodynamics Part 2 Flashcards
4 examples of intensive physical properties
Boling Point
Color
Density
Melting Point
a positive pressure greater than atmospheric or barometric pressure using ambient pressure as the reference
gauge pressure
caused by the collisions of the molecules of the substance with the walls of a container
pressure
measure of force exerted per unit area on the walls of a container
pressure
directly proportional to the average amount of thermal kinetic energy of the particles in a substance
kelvin
weight of a unit volume of a substance
specific weight
this concept assumes that the matter in a body is continuously distributed in the entire region of space it occupies
Concept of Continuum
heavy fluids such as _______________ are used if large pressure differences are anticipated
mercury
pressure that is exerted by the fluid due to the force of gravity
hydrostatic pressure
Any characteristic of a substance is called a
property
reciprocal of density
specific volume
this pressure is almost always used
absolute pressure
used to measure small and moderate pressure differences
manometer
defined as the volume occupied by per unit mass of a substance
specific volume
Pressure in a fluid ___________ with depth because more fluid rests on deeper layers
increases
4 examples of extensive physical properties
Volume
Length
Mass
Shape
measure of the average kinetic energy of the particles in a system
temperature
measured referenced to absolute vacuum (zero pressure)
absolute pressure
Some examples of specific properties are?
specific volume and specific total energy
defined as the mass per unit volume
denisty
a negative pressure less than atmospheric or barometric pressure using ambient pressure as the reference
vacuum pressure
independent of the amount of liquid, the shape of the container, or the cross-sectional area
hydrostatic pressure
ratio of the density of a substance to the density of some standard substance at a specified temperature
specific gravity
