If K is Boltzman's constant the quantity `(PV)/(KT)` represents
(A) mass of gas
(B) number of moles of gas
(C) energy of gas
(D) number of molecules of gas

What is the relation between mass and number of moles of the gas ?

The number of molecules in a gram-mole of molecule of a gas is called

The numerical value of N/n (where N is the number of molecules in a give sample of gas and n is the number of moles of gas) is

For a gas gamma = 9//7 . What is the number of degrees of freedom of the molecules of this gas ?

For a gas, gamma = 9//7 . What is the number of degrees of freedom of the molecules of this gas ?

If "a" gas expands at constant temperature, it indicates that (A) kinetic energy of molecules remains the same (B) number of the molecules of gas increases (C) kinetic energy of molecules decreases (D) pressure of the gas increase
