(b) number of moles
(c) volume
(d) none of these
Chooose the correct option
1. (a), (b)
2. (b) , (c)
3. (c) , (d)
4. (d) only
A vessel of volume V contains a mixture of 1 mole of hydrogen and 1 mole of oxygen (both considered ideal). Let denotes the fraction of molecules with a speed between v and (v+dv) with (v)dv similarly for oxygen. Then,
1. (v) = f(v) obeys the Maxwell's distribution law.
2. will obey Maxwell’s distribution law separately.
3. neither nor will obey Maxwell’s distribution law.
4. and will be the same.
Maxwell's speed distribution graph is drawn as shown below. The most probable speed of the gas molecules is:
1. 4 km/s
2. Between 3 km/s and 1 km/s
3. Any value between 2 km/s and 6 km/s
4. More than 4 km/s
Maxwell's velocity distribution curve is given for two different temperatures. For the given curves-
