A vessel contains 14 g (7 moles) of hydrogen and 96 g (9 moles) of oxygen at S.T.P. Chemical reaction is induced by passing electric spark in the vessel till one of the gases is consumed. The temperature is brought back to it\'s starting value 273 K. The pressure in the vessel is

A jar contains a gas and few drops of water at T K. The pressure in the jar is 830 mm of mercury. The temperature of jar is reduced by 1%. The saturated vapour pressure of water at the two temperatures are 30 mm and 25 mm of mercury. Then the new pressure in the jar will be

Molar specific heat of oxygen at constant pressure C_P = 7.2 cal/mol° C and R = 8.3 Joule/ mol K. At constant volume, 5 mol of oxygen is heated from 10°C to 20°C, the quantity of heat required is approximately

One mole of an ideal gas required 207 J heat to raise the temperature by 10 K when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by the same 10 K, the heat required is
(Given the gas constant R = 8.3 J/mol-K)

The expansion of an ideal gas of mass m at a constant pressure P is given by the straight line D. Then the expansion of the same ideal gas of mass 2m at apressure P/2 is given by the straight line

An experiment is carried on a fixed amount of gas at different temperatures and at high pressure, such that it deviates from the ideal gas behaviour. The variation ofPV/RT with P is shown in the diagram. The correct variation will correspond to

The graph which represents the variation of mean kinetic energy of molecules with temperature t°C is

The expansion of unit mass of a perfect gas at constant pressure is shown in the diagram. Here

Pressure versus temperature graph of an ideal gas of equal number of moles of different volumes are plotted as shown in figure. Choose the correct alternative
