Problem: A sample of monatomic ideal gas containing 6.02´1023 atoms occupies a volume of 2.24´10-2 m3 at a pressure of 1.01´105 Pa. With the volume held constant, the gas is cooled until the atoms are moving at a root-mean-square speed of 402 m/s. The mass of each atom is 6.646´10-27 kg.

  1. What is the initial temperature of the gas?
  2. What is the final temperature of the gas?
  3. What is the change in entropy of the gas?
