Question 334: Thermodynamics & KTG

Question

In van der Waal equation $$\left[ {P + {a \over {{V^2}}}} \right]$$ [V $$-$$ b] = RT; P is pressure, V is volume, R is universal gas constant and T is temperature. The ratio of constants $${a \over b}$$ is dimensionally equal to :

Accepted Answer

From the equation
$$[a] \equiv [P{V^2}]$$
$$[b] \equiv [V]$$
$$ \Rightarrow \left[ {{a \over b}} \right] \equiv [PV]$$

Answer

$${P \over V}$$

Answer

$${V \over P}$$

Answer

PV

Answer

PV3

Thermodynamics & KTG

In van der Waal equation $\left[ {P + {a \over {{V^2}}}} \right] [V - b] = RT; P is pressure, V is volume, R is universal gas constant and T is temperature. The ratio of constants {a \over b}$ is dimensionally equal to :
