At 4°C, a gas occupies 200 ml and the same amount of gas at the same pressure occupies 300 ml at 144 — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Let the absolute zero temperature be -x °C. According to Charles's law: V1 / (t1 + x) = V2 / (t2 + x) => 200 / (4 + x) = 300 / (144 + x) => 2 * (144 + x) = 3 * (4 + x) => 288 + 2x = 12 + 3x => x = 276. Therefore, absolute zero is -276°C.
