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.

If P is the pressure and rho is the density of a gas, then P and rho are related as :

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

What is the relation between pressure P and density rho of a gas at constant temperature?

The pressure p and the volume v of a gas are connected by the relation pv^(1.4)=const.Find the percentage error in p corresponding to a decrease of % in v.

If the pressure, temperature and density of an ideal gas are denoted by P.T and rho respectively. The velocity of sound in the gas is

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