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

Slope m = (300 - 200) / (144 - 4) = 100/140 = 5/7. V = mt + c implies 200 = 5/7(4) + c, so c = 1380/7. Absolute zero is t = -c/m = -276°C. Therefore, correct answer is B.
