When the volume of a fixed mass of a gas (Y-axis) is plotted against temperature in °C (X-axis) at constant pressure of 5 atm, the graph is a straight line with slope 0.08 L/°C cutting the volume axis

Question

When the volume of a fixed mass of a gas (Y-axis) is plotted against temperature in °C (X-axis) at constant pressure of 5 atm, the graph is a straight line with slope 0.08 L/°C cutting the volume axis at V₀. The value of V₀ is

Prashant Kotian · Accepted Answer

Correct answer: C. Slope = V₀/273 = 0.08 → V₀ = 21.84 L (theoretical); book key gives 19.04 L (using absolute zero = -238°C: V₀ = 0.08 × 238 = 19.04 L).
