If the average translational kinetic energy of the molecules in one sample of gas has twice the value of that of another sample of the same type of gas, what is the ratio of the rms speeds of the molecules in the first gas to those in the second?
  1.4.0
  2.2.0
  3.1.41
  4.0.71

Question 2

If the average translational kinetic energy of the molecules of one sample of gas has twice the value of that of another sample of gas, how do the internal energies of the two gases compare?
  1.The internal energy of the first gas is greater.
  2.The internal energy of the second gas is greater.
  3.The internal energies of both gases are the same.
  4.We cannot determine which gas has the greater internal energy.
