At what temperature will the RMS speed of oxygen molecules become just sufficient for escaping from the earth's atmosphere?
(Given : Mass of oxygen molecule (m) = 2.76 x 10-26 kg, Boltzmann's constant kB = 1.38 × 10-23 J K-1):
A gas mixture consists of \(2\) moles of O2 and \(4\) moles of Ar at temperature \(T.\) Neglecting all the vibrational modes, the total internal energy of the system is:
A gas mixture consist of 2 moles of and 4 moles of Ar at temperature T. Neglecting all vibrational modes, the total internal energy of the system is:
One mole of an ideal monatomic gas undergoes a process described by the equation constant. The heat capacity of the gas during this process is:
The molecules of a given mass of gas have r.m.s velocity of 200 ms-1 at 27°C and 1.0 x 105 Nm-2 pressure. When the temperature and pressure of the gas are increased to ,respectively, 127°C and 0.05 X 105 Nm-2 , r.m.s velocity of its molecules in ms-1 will become :
A given sample of an ideal gas occupies a volume \(V\) at a pressure \(P\) and absolute temperature \(T\). The mass of each molecule of the gas is \(m\). Which of the following gives the density of the gas?
