Q4 of 65 Page 77

Consider the processes A and B shown in figure. It is possible that


From the graph, we can see that the slope of process B is steeper than that of process A.


Now in an isothermal process, under constant temperature, Pressure(P) x Volume(V) = constant … (i) (according to Boyle’s law)


Differentiating on both sides:


PdV + VdP = 0.


slope = = … (ii)


For an adiabatic process,


PVᵞ = constant


Where,

Three identical adiabatic containers A, B and C contain helium, neon and oxygen respectively at equal pressure. The gases are pushed to half their original volumes.

A rigid container of negligible heat capacity contains one mole of an ideal gas. The temperature of the gas increases by 1°C it 3.0 cal of heat is added to it. The gas may be
