Formula
Convert from celcius to kelvin
Kelvin = celsius +273
convert from kelvin to celcius
celcius = kelvin - 273
20*C to kelvin
20C to Kelvin
K = 20C +273
K = 293K
50K to *C
- C = 50K - 273
* C = -223*C

PV = constant
Boyle’s Law
V/T = constant
Charles’ Law
P/T = constant
Pressure Law
(PV)/ T = constant
General Gas Law
Explain Boyle’s law
For a fixed mass of gas at constant temperature, the pressure is inversely proportional its volume.
At constant temperature the volume of a fixed mass of gas varies inversely with the pressure.
P ∝ 1 / V or P = constant x 1/ V
PV = constant
p1V1 = p2V2
State the law
As the volume of the gas decreases, the gas particles have less room to move around in, and they collide more often with the walls of the container, thus increasing the pressure:
Boyle’s Law
Boyle’s law
Volume is higher
Pressure is _____
Amount of gas is the same
Temperature is the ___
lower
same
Explain Charles’ law
For a fixed mass of gas at constant pressure, the volume is directly proportional to its temperature
The volume of a fixed amount of gas is directly proportional to its temperature(in Kelvin) if the pressure is kept constant
V ∝ T or V/T = constant (when P is constant)
V1/T1 = V2/T2
Charles’ LAW
As volume goes up
Temperature goes ___
up
General Gas Law
The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.
V ∝ T/P
P1V1 / T1 = P2V2 / T2
