Ideal Gas Law
Combined Gas Law
Guy Lussac’s Law
Boyle’s Law pressure times volume = a constant
Charles’ Law: volume is proportional to temperature
Combining the two yields the ideal gas law
Restated Ideal Gas Law: …
nRis a constant, n is the moles and R is the universal gas constant
R =8.31 L kPa /mol K
n = 2.00 moles
T = 500K
R = 8.31 L kPa/moles K
Since n is the same on both
sides of the equation…
278 * 101.3
Guy Lussac’s Law relates pressure and temperature….
To be used when volume and moles
are kept constant
