Which of the following relations is correct for the root-mean-square speed of gas at temperature T?
Where, k= Boltzmann constant, and m= mass of a molecule.
are root mean square, average and most probable speeds of molecules of a gas obeying Maxwellian velocity distribution. Which of the following statements is correct?
For a gas, the r.m.s speed at 800 K is:
(1) Four times the value at 200 K
(2) Half the value at 200 K
(3) Twice the value at 200 K
(4) Same as at 200 K
The curve between absolute temperature and is:
Five molecules of a gas have speeds, 1, 2, 3, 4 and 5 km. The value of the root mean square speed of the gas molecules is:
(1) 3 km (2) km
(3) km (4) 3.5 km
