Pressures and Partial Pressures (PK1) Flashcards
1
Q
What is barometric pressure?
A
Pressure exerted by the weight of gas molecules in the atmosphere above the point of measurement
2
Q
What is partial pressure?
A
The pressure of any particular gas (either alone or in mixture)
3
Q
Dalton’s law of partial pressures
A
Total pressure = (P1 + P2 + P3 + …Pn)
4
Q
Partial pressure equation
A
Partial pressure = Fractional concentration of gas in a mixture x Total pressure
