Solution: Which of the following statements about gases is true?Heavier gas particles effuse faster than lighter gas particles.Particles of different masses have the same average speed at a given temperature.The higher the temperature, the lower the average kinetic energy of a gas sample.At very high pressures, a gas will occupy a larger volume than predicted by the ideal gas law.Particles of lighter masses have a lower average speed then particles of a higher mass at a given temperature

Problem

Which of the following statements about gases is true?

  1. Heavier gas particles effuse faster than lighter gas particles.
  2. Particles of different masses have the same average speed at a given temperature.
  3. The higher the temperature, the lower the average kinetic energy of a gas sample.
  4. At very high pressures, a gas will occupy a larger volume than predicted by the ideal gas law.
  5. Particles of lighter masses have a lower average speed then particles of a higher mass at a given temperature
