=Dalton's Law=

Dalton's Law describes the relationships between the pressure of each gas inside a mixture and the total pressure of that mixture. It says that the total pressure is equal to all the pressures of each gas in the mixture added together. It was created in 1801 by John Dalton. The equation is:

P1 + P2 +... Pn = Ptotal

An example is:

P1 = 5atm P2 = 10atm P3 = 3atm P4 = 20atm

To get the total pressure, you only need to add up all the partial pressures, P1, P2, P3, and P4. 5 + 10 + 3 + 20= 38atm

This graphic demonstrates how Dalton's Law determines the total pressure of our air by adding up all air's component's pressures. J Sams and R Weidner Gas Laws
