Air is cooled from `25^@C` to `0^@C`. Calculate the decrease in rms speed of the molecules.

The temperature of an ideal gas is increased from 27 ^@C to 327 ^@C . It the r.m.s speed of its molecules at 27 ^@C is 200 m//s , then the new r.m.s speed at 600 K will be

Calculate the rms speed of helium atoms at 127^(@) C .

The temperature of an ideal gas is increased from 27^(@)C to 327^(@)C . If the r.m.s. speed of its molecules at 27^(@)C is 200m//s , then the new r.m.s. speed at 600^(@)K will be

Calculate the RMS velocity of hydrogen molecule at 0^@C .

The temperature of an ideal gas is increased from 27 ^@ C to 927^(@)C . The rms speed of its molecules becomes.
