Gaseous State T...

A perfect gas at 27°C is heated at constant pressure to 327°C. If original volume of gas at 27°C is V then volume at 327°C is:

A gas is filled in the cylinder shown in the figure. The two pistons are joined by a string. If the gas is heated, the pistons will:

The capacity of a vessel is 3 litres. It contains 6 gm oxygen, 8 gm nitrogen and 5 gm CO₂ mixture at 27°C. If R = 8.31 J/mole × kelvin, then the pressure in the vessel in N/m² will be: (approx.)

A closed vessel contains 8g of oxygen and 7g of nitrogen. The total pressure is 10 atm at a given temperature. If now oxygen is absorbed by introducing a suitable absorbent the pressure of the remaining gas in atm will be:

Temperature of an ideal gas is T K and average kinetic energy is E = 2.07× 10^-23 T Joule/molecule. Number of molecules in 1 litre gas at S.T.P. will be:

The average kinetic energy per molecule of helium gas at temperature T is E and the molar gas constant is R, then Avogadro’s number is:

Under which of the following conditions is the law PV = RT obeyed most closely by a real gas?

The equation of state of a gas is given by  = + (RT b), where a, b, c and R are constants. The isotherms can be represented by P = AV^m - BV^m - BVⁿ, where A and B depend only on temperature then?

Energy of all molecules of a monoatomic gas having a volume V and pressure P is 3/2 PV. The total translational kinetic energy of all molecules of a diatomic gas as the same volume and pressure is:

At standard temperature and pressure the density of a gas is 1.3 gm/ m³ and the speed of the sound in gas is 330 m/sec. Then the degree of freedom of the gas will be:
