It P is the pressure and `rho` is the density of a gas, then P and `rho` are realted as :

According to Laplace's formula, the velocity (V) of sound in a gas is given by v=sqrt((gammaP)/(rho)) , where P is the pressure and rho is the density of the gas. What is the dimensional formula for gamma ?

If P is the pressure of a gas and rho is its density , then find the dimension of velocity in terms of P and rho .

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

Suppose the pressure p and the density rho of air are related as p//rho^n = const regardless of height ( n is a constant here). Find the corresponding temperature gradient.

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.

A liquid of density rho has to spray with help of aspirator pump at height H from liquid level as shown in figure. If gauge pressure inside bulb is P and density of air is sigma then velocity of air in tube AB is
