Question

Which best defines partial pressure in a mixture of gases?

Answer 1

Answer;

Pressure that is exerted by one gas as if it occupied a container by itself

Explanation;

• Partial pressure refers to the pressure exerted by an individual gas in a mixture of gases.
• According to Dalton's law of partial pressure, the total pressure of a mixture of gases is equivalent to the sum of the partial pressures of the component gases.
• Therefore; The partial pressure of one gas in a mixture of gases, contained in a given volume, is the pressure that one gas would exert if it occupied the entire volume all by itself.

Answer 2

The best definition is pressure that is exerted by one gas as if it occupied a container by itself. 

The partial pressure of one gas in a mixture of gases, contained in a given volume, is the pressure that that one gas would exert if it occupied the entire volume all by itself.
