Definitons
States that the volume of a fixed mixture of gas held at a constant temperature varies inversely with the pressure.
Boyle's Law
Who's formula is this P1/T1 = P2/T2?
Gay-Lussac's Law
P1V1=P2V2
(1.54)(3.12)=(P2)(5.25)
(1.54)(3.12)
-------------- =P2
(5.25)
P2= .0915atm
Oxygen moves from the lungs to the blood and binds to the hemoglobin in red blood cells. Carbon dioxide is released.
Normal gas exchange
A law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.
Charles Law
Who's formula is this V₁ / T₁ = V₂ / T₂?
Charles Law
T1=25 C +273.15=298.15K
T2=50 C +273.15=323.15K
V1=V2 5.0 = V2
-------- -----------
T1 T2 298.15 323.15
V2=5.4
If carbon monoxide enters the blood instead of oxygen, binds to the hemoglobin. Cells in the body begin to die from oxygen deprivation.
Abnormal gas exchange
States that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.

HBOT
States the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant
The ideal gas law

What helps remove any carbon monoxide bound to hemoglobin?
Pressurized oxygen
