One mole of an ideal gas is taken from state $$P$$ to state $$Q$$ by three different processes (i) $$PRQ$$, (ii) $$PSQ$$ and (iii) $$PTQ$$ as shown in the $$p - V$$ diagram. The heat absorbed by the gas is

In a given process on an ideal gas $$ dW=0$$ and $$dQ<0,$$ then the force of gas 

For adiabatic expansion of perfect monoatomic gas , when voulme increases by $$ 24\%$$  ,what is the percentage decrease in pressure ?

The p-V diagram of a gas system undergoing cyclic process is shown here. The work done during isobaric compression is

A gas is compressed at a constant pressure of $$50\, N/m^2$$  from a volume of $$10m^3$$ to a volume of $$4 m^3$$. Energy of 100 J is then added to the gas by heating. Its internal energy is 

The $$p-V$$ plots for two gases during adiabatic process as shown in figure plots $$1$$ and $$2$$ should correspond respectively to.

Two identical vessels $$A$$ and $$B$$ contain equal amount of ideal monoatomic gas. The piston of $$A$$ is fixed but that of $$B$$ is free. Same amount of heat is absorbed by $$A$$ and $$B$$. If $$B's$$ internal energy increases by $$100\ J$$ the change in internal energy of $$A$$ is

A gas at pressure $$p$$ has volume $$V$$. It is adiabatically compressed to volume $$V/32$$. If $$(32)^{1.4} = 128$$, what is the current pressure of the gas?

For an ideal gas with initial pressure and volume $$P_i$$ and $$V_i$$ respectively, a reversible isothermal expansion happens, when its volume becomes $$V_0$$. Then it is compressed to its original volume $$V_i$$ by a reversible adiabatic process. If the final pressure is $$P_t$$ then which of the following statements is true?

The adiabatic Bulk modulus of a diatomic gas at atmospheric pressure is
