Define and describe methods of heat transfer
conduction
convection
radiation
condensation
evaporation
conduction: heat transfers by direct contact (touching)
convection: heat transfers between gases & liquids by fluid movement
radiation: heat transfers not by direct contact between 2 substances
condensation: gas - liquid (a cold soda can has small water droplets around)
evaporation: liquid- gas (puddles disappearing)
describe properties of liquids:
cohesion
adhesion
surface tension
cohesion: attractive forces between like molecules (a U shape, ex. water)
adhesion: attractive forces between unlike molecules ( a n shape, ex.mercury)
surface tension: attractive forces between like molecules on liquid surface
water vapor pressure
acts like any gas exerts it own pressure
water vapor pressure @ body temperature 37 degrees
47 mm Hg
water vapor content @ body temperature 37 degrees
44 mg/L
atmospheric pressure:
760 mmHg
Daltons law
definition:
equation:
each gas in a mixture of gas exerts its own partial pressure
__ X 760 mm Hg= __
altogether= 760 mm Hg
Henrys law
definition:
explain gas law:
the quantity of gas that is dissolved in liquid is proportional to its partial pressure and its solubility/ predicts how much is dissolved
ex. water is more soluble than..
Boyles law
definition:
equation:
explain gas law:
the volume of gas varies inversely with its pressure
(P1 X V1)= (P2 X V2) Multiply then divide
-volume goes up, pressure goes down
-volume goes down, pressure goes up
