Common Questions
What is the ideal gas law?
PV = nRT, where P is pressure, V is volume, n is moles of gas, R is the gas constant (0.0821 L·atm/mol·K), and T is temperature in Kelvin. It relates all four gas variables in one equation.
What is Boyle's Law?
Boyle's Law states that at constant temperature and amount, pressure and volume are inversely proportional: P1V1 = P2V2. If pressure doubles, volume halves.
What is Charles's Law?
Charles's Law states that at constant pressure and amount, volume is directly proportional to temperature (in Kelvin): V1/T1 = V2/T2. As temperature increases, volume increases.
What is the combined gas law?
The combined gas law merges Boyle's, Charles's, and Gay-Lussac's laws: P1V1/T1 = P2V2/T2. It is used when pressure, volume, and temperature all change simultaneously (with constant moles).
