Boyle’s Law: Pressure-Volume Relationship Principle: For a fixed amount of gas at constant temperature, the pressure and volume are inversely proportional: \[ P_1V_1 = P_2V_2 \] Sample Problem: A cylinder containing 2.0 liters of gas at a pressure of 1.0 atm is compressed to a volume of 0.5 liters. What is the new pressure, assuming temperature remains constant? Solution: Applying Boyle’s Law: \[ P_1V_1 = P_2V_2 \] \[ 1.0\, \text{atm} \times 2.0\, \text{L} = P_2 \times 0.5\, \text{L} \] \[ P_2 = \frac{1.0 \times 2.0}{0.5} = 4.0\, \text{atm} \] Answer: The new pressure is 4.0 atm. --- Charles’s Law: Temperature-Volume Relationship Principle: For a fixed amount of gas at constant pressure, the volume and temperature (in Kelvin) are directly proportional: \[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \] Sample Problem: >A gas occupies 3.0 liters at 300 K. What volume will it occupy at 600 K, assuming pressure remains constant? Solution: Using Charles’s Law: \[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \] \[ V_2 = V_1 \times \frac{T_2}{T_1} \] \[ V_2 = 3.0\, \text{L} \times \frac{600\, \text{K}}{300\, \text{K}} = 3.0\, \text{L} \times 2 = 6.0\, \text{L} \] Answer: The gas will occupy 6.0 liters. --- Gay-Lussac’s Law: Pressure-Temperature Relationship Principle: For a fixed amount of gas at constant volume, pressure and temperature are directly proportional: \[ \frac{P_1}{T_1} = \frac{P_2}{T_2} \] Sample Problem: >A sealed container has a pressure of 1.5 atm at 300 K. What will be the pressure at 450 K? Solution: \[ P_2 = P_1 \times \frac{T_2}{T_1} \] \[ P_2 = 1.5\, \text{atm} \times \frac{450}{300} = 1.5 \times 1.5 = 2.25\, \text{atm} \] Answer: The pressure will be 2.25 atm. --- The Ideal Gas Law: PV = nRT This comprehensive law combines the previous relationships and introduces molar quantity: - \( P \): pressure - \( V \): volume - \( n \): number of moles - \( R \): ideal gas Gas Laws Worksheet With Answers 6 constant (8.314 J/(mol·K)) - \( T \): temperature in Kelvin Sample Problem: Calculate the pressure exerted by 2 mol of an ideal gas confined in 10 liters at 300 K.
