Compressed air in the tube of a wheel of a cycle at normal temperature suddenly starts coming out of the puncture. The air inside

If $$C_p$$ and $$C_v$$ are the molar specific heats of a gas at constant pressure and volume respectively then the ratio of adiabatic and isothermal modulii of elasticity will be

Four curves A, B, C and D are drawn for given mass of gas.  The curves which represent adiabatic and isothermal expansion are respectively

Consider a hypothetical gas temperature of which increases to $$\sqrt{2}$$ times when compressed adiabatically to half the volume. Its equation can be written as

In free expansion of a gas the internal energy of the system

When a liquid is heated retaining its liquid state, then its molecules gain

The volume of a gas is reduced to $$\dfrac{1}{4}$$ of its initial volume adiabatically at $$27^o$$. The final temperature of the gas (if $$\gamma= 1.4$$) will be

The relation between $$P$$ and $$T$$ for monoatomic gas during adiabatic process is $$P \propto T$$ $$^c$$. The value of c is

What is the value of $$\dfrac{dP}{P}$$ for adiabatic expansion of the gas?

A gas is enclosed in a vessel of volume 1000 cc at a pressure of 72.6 cm of Hg. It is being evacuated with the help of a piston pump, which expels 10% gas in each stroke. The pressure after the second stroke will be nearest to
