densities ✘ specific weights ✘ molecular weights ✘ gas characteristic constants ✔

mass does not cross boundaries of the system, though energy may do so ✘ neither mass nor energy crosses the boundaries of the system ✘ both energy and mass cross the boundaries of the system ✘ mass crosses the boundary but not the energy ✔

only one value of specific heat ✘ two values of specific heat ✘ three values of specific heat ✘ no value of specific heat ✔

Joule ✘ Boyle ✘ Regnault ✘ Charles ✔

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 ✔

+ ve ✘ -ve ✘ zero ✘ maximum ✔

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 ✔

Avogadro ✘ Dalton ✘ Gas law ✘ Law of thermodynamics ✔
