The ratio of the specific heats CpCv = in terms of degrees of freedom (n) is given by
(1) (1 + 2n )
By the law of equipartition of energy, for one mole: U = n2RT
Cv = n2R, Cp = Cv + R = ( n2 + 1 )R
= CpCv = 1 + 2n
Answer: (1)
The mean free path of molecules of a gas, (radius r) is inversely proportional to
In the given (V - T) diagram, what is the relation between pressure P1 and P2? [figure]
The amount of heat energy required to raise the temperature of 1 g of Helium at NTP, from T1 K to T2 K is
In a vessel, the gas is at pressure P. If the mass of all the molecules is halved and their speed is doubled, then the resultant pressure will be
At 10 the value of the density of a fixed mass of an ideal gas divided by its pressure is x. At 110 this ratio is
The equation of state for 5 g of oxygen at a pressure P and temperature T, when occupying a volume V, will be (where R is the gas constant)
To find out degrees of freedom, the expression is
