The difference between volume and pressure coefficients of an ideal gas is :

A gas in an airtight container is heated from 25$$^{o}$$C to 90$$^{o}$$C. The density of gas will :

The molar gas constant is the same for all gases because at the same temperature and pressure, equal volumes of gases have the same :

If the volume of the gas is to be increased by 4 times :

Three closed vessels A, B and C are at the same temperature T and contain gases which obey Maxwell distribution law of velocities. Vessel A contains $$O_2$$, B only $$N_2$$ and C mixture of equal quantities of $$O_2$$ and $$N_2$$. If the average speed of $$O_2$$ molecules in vessel A is $$V_1$$ and that of $$N_1$$ molecules in vessel B is $$V_2$$, then the average speed of the $$O_2$$ molecules in vessel C is

A gas at temperature 27$$^{0}$$C and pressure 30 atmospheres is allowed to expand to one atmospheric pressure. If the volume becomes 10 times its initial volumes, the final temperature becomes :

The Universal gas constant may be expressed as :

a) 8.31 J/mole-K         c) 2.00 J/mole-K

b) 8.31 cal/mole-K       d) 2.00 cal/mole-K

The parameter that determine the physical state of gas are :

a) Pressure                  b) Volume

c) Number of moles    d) Temperature

16 gm of $$O_{2}$$ gas and x gm of $$H_{2}$$ gas occupy the same volume at the same temperature and pressure. Then x is :
