Certain amount of an ideal gas is taken from its initial state 1 to final state 4 through the paths 1 $$\to$$ 2 $$\to$$ 3 $$\to$$ 4 as shown in figure. AB, CD, EF are all isotherms. If v_{p} is the most probable speed of the molecules, then

Consider a thermodynamic process where integral energy $$U = A{P^2}V$$ (A = constant). If the process is performed adiabatically, then

One mole of a diatomic ideal gas undergoes a process shown in P-V diagram. The total heat given to the gas (ln 2 = 0.7) is

One mole of an ideal monoatomic gas expands along the polytrope PV^{3} = constant from V_{1} to V_{2} at a constant pressure P_{1}. The temperature during the process is such that molar specific heat $${C_V} = {{3R} \over 2}$$. The total heat absorbed during the process can be expressed as
