Problem

The graph (below) shows the distribution of molecular velocities.  How many of the statements are true?

  • At a given temperature, curve A represents gas particles with the smallest molar mass
  • For a given gas sample, curve D represents the highest temperature
  • At a given temperature, curve D represents gas particles with the highest molar mass
  • For a given gas sample, the broader the velocity distribution, the lower the temperature
