Molecular Speeds (rms, Average, Most Probable): JEE Questions & Solutions

The r.m.s. speed of oxygen molecules at 47^ C is equal to that of the hydrogen molecules kept at ^ C. (Mass of oxygen molecule/mass of…

The ratio of vapour densities of two gases at the same temperature is 425, then the ratio of r.m.s. velocities will be:

At which temperature does the r.m.s. velocity of a hydrogen molecule equal that of an oxygen molecule at 47^ C?

At which temperature does the r.m.s. velocity of a hydrogen molecule equal that of an oxygen molecule at 47 °C?

Given below are two statements: Statement I: The temperature of a gas is -73^ C. When the gas is heated to 527^ C, the root mean square…

The root mean square velocity of molecules of gas is:

At 300 K, the rms speed of oxygen molecules is +5 times to that of its average speed in the gas. Then, the value of will be (used = 227):

The temperature of an ideal gas is increased from 200 K to 800 K. If r.m.s. speed of gas at 200 K is v0, then the r.m.s. speed of the gas…

The ratio of speed of sound in hydrogen gas to the speed of sound in oxygen gas at the same temperature is:

Three vessels of equal volume contain gases at the same temperature and pressure. The first vessel contains neon (monoatomic), the second…

The root mean square speed of molecules of nitrogen gas at 27^ C is approximately: (Provided that mass of a nitrogen molecule = 4.6 10^-26…
