tions Cons: Only applicable at constant temperature and amount Charles’s Law Definition: Charles’s Law describes the direct proportionality between volume and temperature (in Kelvin) at constant pressure and amount: \[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \] Application in Pract
blem: A 2.0 L container holds 0.5 mol of a gas at 300 K. What is its pressure? Solution: Use PV = nRT P = (nRT) / V P = (0.5 mol × 0.0821 L·atm/mol·K × 300 K) / 2.0 L P = (12.315) / 2.0 = 6.1575 atm Answer: The pressure is approximately 6.16 atm. Tips for Mastering Gas Law T
