The unit of universal gas constant is

A

`"watt"//"K"`

B

`"dyne"//^(circ)"C"`

C

`"erg"//"K"`

D

`"newton"//^(circ)"R"`

Text Solution

Verified by Experts

The correct Answer is:
C
Ideal gas law is given by
`" "pV=RT`
`therefore" "R=(pV)/(T)=("Unit of work")/("Unit of temperature")`
`rArr" "R=("erg")/(K)`
