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

Water is cooled from 4^(@)C to 0^(@)C it:

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

When water is cooled from 4^@C to 0^@C its volume decreases.

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