The value of Boyle's Law constant (in S.I. unit) for 200 ml of gas at 1.2 atm is about — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Boyle's law constant K = P * V. In S.I. units, pressure is in Pa (N/m^2) and volume is in m^3, making the unit of K equivalent to Joules (J). P = 1.2 atm = 1.2 * 101325 Pa = 121590 Pa. V = 200 ml = 200 * 10^-6 m^3. K = P * V = 121590 * 200 * 10^-6 = 24.318 J ≈ 24.3 J.
