Question

dimensional formula of universal gas constant is equivalent to

Answer 1

according to gases
formula,
PV = nRT
where P is the
pressure, V is the
volume, n is the no of
mole, R is gas
constant and T is
temperature.
now , R = PV/nT
dimension of pressure
= [ML^-1T^-2]
dimension of volume
= [ L^3 ]
dimension of mole =
no dimension
dimension of
temperature = [ K]
now , dimension of R
=[ML^-1T^-2][L^3]/[K]
=[ ML²T⁻²K⁻¹]
