An ideal gas equation can be written as ...

An ideal gas equation can be written as `P = rho R T/ M_0` where `rho` and M are resp.

A

Number density , molar mass

B

Mass density , molar mass

C

Number density , mass of the gas

D

Mass density , mass of the gas

Text Solution

Verified by Experts

The correct Answer is:
B
From the gas equation
` Pv = nRT`
` rArr p = (1)/(v) (m)/(M_0) RT = ((m)/(v)) ((RT)/(M_0)) `
` rArr p = (rho RT)/(M_0) `
` rArr rho = ( m)/(v) ` = mass density
` M_0 ` = molar mass

An ideal gas expands following a relation (P^(2))/(rho) = constant, where P = pressure and rho = density of the gas. The gas is initially at temperature T and density rho and finally its density becomes (rho)/(3) . (a) Find the final temperature of the gas. (b) Draw the P – T graph for the process.

If c_(p) and c_(v) are the principal specific heats of an ideal gas in cal/gm .^(@)C,rho is the density, P is the pressure and T is the temperature of the gas, then Mayer's relation is

If an additional pressure Delta p of a saturated vapour over a convex spherical surface of a liquid is considerably less than the vapour pressure over a plane surface, then Delta p = (rho_v//rho_l) 2 alpha//r , where rho_v and rho_l) are the densities of the vapour and the liquid, alpha is the surface tension, and r is the radius of curvature of the surface. Using this formula, find the diameter of water droplets at which the saturated vapour pressure exceeds the vapour pressure over the plane surface by eta = 1.0 % at a temperature t = 27 ^@C . The vapour is assumed to be an ideal gas.
