Interpretation:
The volume of dry gas when the volume of wet gas collected over water is
Concept introduction:
Ideal gas is defined as the gas in which the collisions between the molecules and the atoms are perfectly elastic and there are no intermolecular attractive forces found between them.
Answer to Problem 72E
The volume of dry gas when the volume of wet gas collected over water is
Explanation of Solution
The relation between the initial and final pressure, volume and temperature of gas is shown below.
Where,
•
•
•
•
•
•
The above equation can be rearranged for the value of final volume
The volume of wet gas is
The vapor pressure of water is
According to the Dalton’s law of partial pressure, the total pressure is calculated as shown below.
The above formula can be rearranged for the value of initial pressure
Substitute the value of vapor pressure and total pressure in the above expression.
The initial temperature is
Conversion of temperature from Celsius to Kelvin is done as shown below.
Therefore,
So, the initial and final temperature are
The value of initial volume is
Substitute the values of initial and final temperature, pressure and volume into the equation (2).
Therefore, the final volume is
The volume of dry gas is
