    If the dimension of a physical quantity is given by [MaLbTc][M^aL^bT^c] then the physical quantity will be

  • Question 2
    1 / -0

    The equation of state of some gases can be expressed as (P+aV2)(Vb)=RT\left(P+\dfrac{a}{V^{2}}\right)\left(V-b\right)=RT. Here P is the pressure, VV is the volume, TT is the absolute temperature and a,b,Ra,b,R are constant. The dimensions of aa are:
