At constant pressure , which of the following is true ?

A

`cpropsqrtrho`

B

`cprop(1)/(rho)`

C

`cproprho`

D

`cprop(1)/(sqrtrho)`

Text Solution

Verified by Experts

The correct Answer is:
D
Pressure due to an ideal gas is given by ,
`p=(M)/(3V)c^(2)`
Putting `(M)/(V)=rho` , the density of gas .
`p=(1)/(3)rhoc^(2)rArrc=sqrt(((3p)/(rho)))`
`therefore" " cprop(1)/sqrt(rho)`
