Thermodynamics-I Set 3

the molecular weights of all the perfect gases occupy the same volume under same conditions of pressure and temperature ✘ the sum of partial pressure of mixture of two gases is sum of the two ✘ product of the gas constant and the molecular weight of an ideal gas is constant ✘ gases have two values of specific heat ✔ all systems can be regarded as closed systems. ✔

zero ✘ maximum ✔ minimum. ✔

depends on the mass of the system like volume ✘ does not depend on the mass of the system, like temperature, pressure, etc. ✘ is not dependent on the path followed but on the state ✘ is dependent on the path followed and not on the state ✔ is always constant. ✔

C/Cv ✘ Cv/Cp ✘ Cp ✘ Cp + Cv ✔ Cp x Cv ✔
