laws ch 13 Flashcards
Gas behavior- what are the four variables affect the behavior of a gas
P- pressure, V- volume, N- moles, T- temperature
whoo studied that the volume of a sample at a given temperature caries inversely with the applied pressure
Boyle
what are the two variables that are studied in Boyle’s law
pressure and volume
what is the equation for Boyle’s law
V i x P i = V f xP f
when does three dimensional space shrink and when does is expand
when there is more pressure put on it and less pressure put on it. therefore it works inversely
when the theoretical temperature at which a gas would have zero volume and no pressure
absolute zero
who studied that the volume occupied by any sample of gas at a constant pressure is directly proportional to the absolute temperature
Charle’s Law
what are the two variables in Charle’s law
Volume and Temperature
equation for Charle’s Law
V i / T i = V f / T f
what happens when gas gets hotter and cooler
if it gets hotter then atoms move faster, if it cools then the volume reduces
who studied that the equal volumes of any two gases at the same temperature and pressure contain the same number of molecules
Avogadro
Equation for Avogadro’s Law
V i / n i = V f / n f
if more gas is added then what happens to the volume
it increases
if gas is removed then the volume does what
it decreases
who studied that the pressure exerted on a gas at a constant volume and amount is directly proportional to the temperature
Gay Lussac’s Law
