e) If v= at? + bt, find out the dimension of a a
Luontor of = 31-41 + 2K​

Answer 1

Answer:

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}R=TPV

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

=[ ML²T⁻²K⁻¹]
