Key Gas Laws Covered in Practice Problems
Boyle’s Law
Boyle’s Law states that, at constant temperature, the pressure and volume of a gas are inversely proportional:
\[ P_1 V_1 = P_2 V_2 \]
Charles’s Law
Charles’s Law indicates that, at constant pressure, the volume of a gas is directly proportional to its temperature:
\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]
Gay-Lussac’s Law
This law states that, at constant volume, the pressure of a gas is directly proportional to its temperature:
\[ \frac{P_1}{T_1} = \frac{P_2}{T_2} \]
Avogadro’s Law
It asserts that equal volumes of gases at the same temperature and pressure contain an equal number of molecules:
\[ V_1 / n_1 = V_2 / n_2 \]
Ideal Gas Law
A comprehensive law combining all the above:
\[ PV = nRT \]
where:
- \( P \) = pressure
- \( V \) = volume
- \( n \) = number of moles
- \( R \) = ideal gas constant
- \( T \) = temperature (Kelvin)

Sample Gas Laws Practice Problems with Answers
Problem 1: Boyle’s Law
Question: A 2.0 L container of gas is under a pressure of 1.0 atm. What will be the pressure if the volume is decreased to 1.0 L at constant temperature?
Solution:
Using Boyle’s Law \( P_1 V_1 = P_2 V_2 \)
\[ P_2 = \frac{P_1 V_1}{V_2} = \frac{1.0\, \text{atm} \times 2.0\, \text{L}}{1.0\, \text{L}} = 2.0\, \text{atm} \]
Answer: The pressure will be 2.0 atm.
Problem 2: Charles’s Law
Question: A balloon has a volume of 3.0 L at 300 K. What will be its volume at 600 K, assuming pressure remains constant?
Solution:
Using Charles’s Law \( V_1 / T_1 = V_2 / T_2 \):
\[ V_2 = V_1 \times \frac{T_2}{T_1} = 3.0\, \text{L} \times \frac{600\, \text{K}}{300\, \text{K}} = 6.0\, \text{L} \]
Answer: The volume will be 6.0 L.
