PV/T at y-intercept (ideal gas limit): 0.259 J/K
Mass of gas: 1.00 × 10⁻³ kg
a. What does the dotted plot signify?
The dotted plot represents the ideal gas behavior (PV/T = constant).
b. Which is true: T₁ > T₂ or T₁ < T₂?
T₁ < T₂ (The higher curve corresponds to higher temperature)
c. What is the value of PV/T where the curves meet on the y-axis?
For 1.00×10⁻³ kg of O₂: 0.259 J/K (nR where n = moles of gas)
d. For hydrogen, what mass yields the same PV/T at the y-intercept?
0.0631 × 10⁻³ kg (Calculated using molecular mass ratio)
