(a)
Interpretation:
The change in the pressure
Concept introduction:
Boyle’s law which relates pressure and temperature states that when temperature is kept constant for a gas then the pressure and temperature follows the inverse relation. According to Boyle’s law, relation between pressure and volume is written below.

Answer to Problem 11E
The pressure decreases with increase in volume from
Explanation of Solution
According to the equation of Boyle’s law if volume is increased for a particular or constant temperature then the pressure of the gas will be decreased to keep the
Where,
•
•
•
•
•
The given values of the initial volume
Substitute the values of
Therefore, decrease in pressure is
The pressure decreases by the factor of
(b)
Interpretation:
Change in the pressure
Concept introduction:
Gay Lussac’s law one of the

Answer to Problem 11E
The pressure
Explanation of Solution
The relation given by Gay Lussac’s for the gaseous molecule is stated below.
Where,
•
•
•
•
•
Ratio of pressure and temperature is constant. Pressure will be increased with the increase in value of temperature to keep the ratio
Conversion of initial temperature
Conversion of final temperature
Substitute the value of
Therefore, the pressure will increase in the container.
Increase in pressure
(c)
Interpretation:
The change in the pressure
Concept introduction:

Answer to Problem 11E
Increase in pressure
Explanation of Solution
The relation given by all the variables of a gas is stated as below.
According to the relation given above pressure is directly proportional to the number of moles. Pressure will be decreased with the decrease in number of moles to maintain the gas law when all other variables are kept constant.
Gas law is written below.
Where,

•
The number of moles,
The number of moles,
Substitute the given values of
Therefore, the pressure will increase in the container.
The pressure will increase in the container.
