The $$P-T$$ diagram for an ideal gas is shown in Fig., where $$AC$$ is an adiabatic process, find the corresponding $$P-V$$ diagram.

State the equation corresponding to 8 g of $$O_{2}$$ is then

A certain quantity of ideal gas takes up $$6$$ $$\mathrm { J }$$ fheat in process $$AB$$ and $$360J$$ in process AC. The adiabatic constant for the gas is:

The pressure and density of a diatomic gas ($$\gamma = 7/5$$) change from $$(P_{1}, d_{1}) to (P_{2}, d_{2})$$ adiabatically  . If $$d_{2}/d_{1}=32$$, then what is the value of $$P_{2}/P_{1}$$?

During the adiabatic change of ideal gas, The relation between the pressure and the density will be -

The internal energy change in a system that has absorbed $$2\ Kcal$$ of heat and done $$500\ J$$ of work is

One mole gas is first cooled from 300 K to 150 K at constant volume and then heated from 150 K to 300 K at constant pressure. The net heat absorbed by the gas is

A constant volume gas thermometer shows pressure reading of 50 cm and 90 cm of mercury at 0$$^{0}C$$ and 100$$^{0}C$$ respectively. When the pressure reading is 60 cm  of mercury, the temperature is:-

Dry air at $$15C$$ and $$10$$ $$atm$$ is suddenly released in atmospheric pressure. Find the final temperature of the air.  (for air, $$\cfrac{Cp}{Cv}=1.41$$)
