RCP 100 Physical Principles of Respiratory Care Flashcards
Solid
Uniformed with fixed volume and shape
strong mutual force between atoms
pg 88
Liquids
Have fixed volume, takes shape of container
strong mutual force
pg89
Gases
No fixed volume or shape
weak molecular attraction
molecules move rapidly with random collisions pg 88
Plasma
Neutral atoms, free electrons, atomic nuclei
pg89
Internal energy are made up of?
Kinetic- energy of motion
Potential- stored energy
pg 89
What is kinetic energy?
energy of motion
pg 89
What is potential energy?
stored energy, energy of the position
pg 89
First law of thermodynamics
The hotter air will move to the cooler air til it is equal
like diffusion
pg 89
Conduction
physical contact and transfer of heat
pg 89
Convection
liquid and gas heat transfer happened here
forcing heat in
pg 89
Radiation
no physical contact between heat
pg 89
Vaporization
liquid to gas
pg 89
Evaporation
liquid to gas, heat taken from air around liquid, cooling the air
pg 90
Condensation
gas to liquid, gives heat to the air
pg 90
Relationship between temperature and kinetic energy
The hotter it is the more gas molecules bounce around
pg 89
