(a)
Interpretation:
The following table is to be completed by assuming the gas at a constant temperature.
2.0atm | 3.0L | 8.0atm | ? |
Concept Introduction:
The concept of Boyle's law will be used. This is represented as-
Or,
Here, P is pressure and V is the volume of the gas.

Answer to Problem 7.51P
2.0atm | 3.0L | 8.0atm | 0.75L |
Explanation of Solution
According to Boyle's law, the pressure of the ideal gas is inversely proportional to the volume of the ideal gas at constant temperature. This is represented as
Or,
Or,
Given that −
P1, initial pressure = 2.0atm
V1, initial volume = 3.0L
P2, final pressure = 8.0atm
Put the above values in equation (1),
Final volume = 0.75 L
(b)
Interpretation:
The following table is to be completed by assuming the gas at a constant temperature.
55 mmHg | 0.35 L | 18 mmHg | ? |
Concept Introduction:
The concept of Boyle's law will be used. This is represented as-
Or,
Here, P is pressure and V is the volume of the gas.

Answer to Problem 7.51P
55mmHg | 0.35L | 18mmHg | 1.07L |
Explanation of Solution
According to Boyle's law, the pressure of the ideal gas is inversely proportional to the volume of the ideal gas at a constant temperature. This is represented as
Or,
Or,
Given that −
P1, initial pressure = 55mmHg
V1, initial volume = 0.35mL
P2, final pressure = 18mmHg
Put the above values in equation (2)
Final volume = 1.07L
(c)
Interpretation:
The following table is to be completed by assuming the gas at a constant temperature.
705mmHg | 215mL | ? | 1.52L |
Concept Introduction:
The concept of Boyle's law will be used. This is represented as-
Or,
Here, P is pressure and V is the volume of the gas.

Answer to Problem 7.51P
705mmHg | 215mL | 100mmHg | 1.52L |
Explanation of Solution
According to Boyle's law, the pressure of the ideal gas is inversely proportional to the volume of the ideal gas at a constant temperature. This is represented as
Or,
Or,
Given that −
P1, initial pressure = 705mmHg
V1, initial volume = 215mL
Or,
V2, final pressure = 1.52 L
Put the values in the above equation,
Final pressure = 100mmHg
The final table is −
705mmHg | 215mL | 100mmHg | 1.52L |
