Which of the following is NOT a characteristic of an ideal gas? A) They have tiny volumes compared with the collective volume they occupy. B) They move constantly and randomly. C)... Which of the following is NOT a characteristic of an ideal gas? A) They have tiny volumes compared with the collective volume they occupy. B) They move constantly and randomly. C) They have an average kinetic energy that is independent of absolute temperature. D) They engage in elastic collisions with the walls of their container and other gas molecules.
Understand the Problem
The question is asking to identify which option does not describe a characteristic of an ideal gas. This requires an understanding of the kinetic theory of gases and the properties of ideal gases.
Answer
C) They have an average kinetic energy that is independent of absolute temperature.
The final answer is C) They have an average kinetic energy that is independent of absolute temperature.
Answer for screen readers
The final answer is C) They have an average kinetic energy that is independent of absolute temperature.
More Information
For an ideal gas, the average kinetic energy of the gas particles is directly proportional to the absolute temperature. This means it depends on, not independent of, the temperature.
Tips
A common mistake is thinking that kinetic energy is independent of temperature; however, in reality, kinetic energy is determined by temperature.
