when pressure is constant, volume and temp are directly related
when one goes up/down so does the other

Charles law formula
V1/T1= V2/T2
New cards
8
Boyle’s law
when temp is constant pressure and volume are inversely related ( when one goes up the other goes down)
New cards
9
Boyles formula
P1•V1=P2•V2

10
Gay-Lussacs law
\
when V is constant pressure and Temp are directly related
New cards
11
Gay-Lussacs law formula
P1/t1=p2/t2

12
avagadros law
volumes of gas at same temp/pressure have = # of particles
New cards
13
Avagadros formula
V1/n1=V2/n2 ( directly realated)

How to convert Celcius to kelvin
C°+ 273= K

16
celsius to fahrenheit
F°= 1.8 C° +32
New cards
17
Fahrenheit to celsius
C°= F°-32/1.8

18
Daltons law
Partial=pressure if each gas in a mixture
ptotal= p1+p2+p3…
New cards
19
combined law
p1 v1/T1= p2 v2/T1

20
ideal gas
an imaginary gas that perfectly fits all assumptions of kinetic molecular theory
PV=nRT
New cards
21
kinetic molecular theory
Gas particles in constant rapid motion
The temperature depends on kinetic energy
New cards
22
STP
temp- 0 C° or 293.15 K
Pressure- 1 Atm

New cards
23
Real gas
take up space have attraction
does not fit with kinetic theory
change more at high pressure and low temp
closest gas
New cards
24
when do gases act most ideal
at high temps and low pressures
New cards
25
what is attraction like in ideal gases
there is no attractive or repulsive forces
New cards
26
how does energy behave in ideal gases
no energy is lost in collisions
New cards
27
how does a barometer work
The mercury sits in a circular, shallow dish surrounding the tube. The mercury in the tube will adjust itself to match the atmospheric pressure above the dish. As the pressure increases, it forces the mercury up the tube.
