Question

Dimensional formula of R gas constant

Answer 1

we know ,

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]
$R = \frac{PV}{T}$

now , dimension of R =[ML^-1T^-2][L^3]/[K]
=[ ML²T⁻²K⁻¹]

Answer 2

Answer:

Explanation:

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]
