Question

At what absolute temperature the pressure of He gas in a definite volume become equal to zero ?

• A. $\frac{a}{R} \times \frac{(V_{m} - b)^{2}}{{V_{m}}^{2}}$
• B. $\frac{a}{R} \times \frac{(V_{m} - b)}{{V_{m}}^{2}}$
• C. $\frac{a}{R} \times \frac{(V_{m} - b)^{2}}{V_{m}}$
• D. $\frac{aV_{m}}{R}$

Answer 1

Answer: (B)

$\frac{a}{R} \times \frac{(V_{m} - b)}{{V_{m}}^{2}}$

Answer 2

$\left( P + \frac{a}{{V_{m}}^{2}} \right)$ (v_m – b) = RT

when P = O, T = $\frac{a}{R}$ × $\frac{\left( v_{m} - b \right)}{{V_{m}}^{2}}$
