GATE Previous Year Questions on Basic Concepts of Thermodynamics & Zeroth Law | PYQ Practice

Which one of the following is an intensive property of a thermodynamic system? The internal energy of an ideal gas is a function of The Vander-waals equation of state is (𝒑+𝒂/𝒗^𝟐 )(𝒗−𝒃)=𝑹𝑻 where 𝒑 is pressure, 𝒗 is specific volume, 𝑻 is temperature and 𝑹 is characteristic gas constant. The SI unit of 𝒂 is __________. The specific heats of an ideal gas depend on its The definition of 1 K as per the internationally accepted temperature scale is Consider a mixture of two ideal gases, X and Y, with molar masses ‾𝑴_𝑿=𝟏𝟎" kg/kmol"and ‾𝑴_𝒀=𝟐𝟎" kg/kmol", respectively, in a container. The total pressure in the container is 𝟏𝟎𝟎" kPa", the total volume of the container is 𝟏𝟎" " "m" ^𝟑and the temperature of the contents of the container is 𝟑𝟎𝟎" K". If the mass of gas-X in the container is 𝟐" kg", then the mass of gas-Y in the container is ____ kg. (Rounded off to one decimal place) Assume that the universal gas constant is 𝟖𝟑𝟏𝟒" " 〖"J kmol" 〗^(−𝟏) "K" ^(−𝟏).
