FAQs: Answering Your Burning Questions
Is partial pressure the same for all gases in a mixture?
No, it’s not. Each gas contributes differently to the total pressure, leading to distinct partial pressures.
Can partial pressure be measured directly?
Yes, sophisticated instruments like a manometer can directly measure partial pressure.
How does altitude affect partial pressure?
As you ascend, atmospheric pressure decreases, impacting the partial pressure of gases.
Are there exceptions to Dalton’s Law?
In certain conditions, deviations from Dalton’s Law can occur, often under high pressure or low temperature.
Can partial pressure be greater than total pressure?
No, according to Dalton’s Law, the sum of partial pressures cannot exceed the total pressure.
Why is partial pressure important in scuba diving?
Understanding partial pressure is crucial in preventing decompression sickness during scuba diving.
