Concept explainers
Interpretation:
The assumption accepted for ideal gases but not applied for real gases have to be found.
Concept Introduction:
Assumptions of the kinetic molecular theory:
- Gases consist of tiny particles.
- The volume occupied by the gas molecules is negligible compared to the volume of the gas.
- There is no force of attraction between gas particles.
- For the gas particles, the average kinetic energy is directly proportional to the absolute temperature.
Answer to Problem 7STP
Among the above assumptions, the assumption that there is no force of attraction between gas particles is responsible for the behavior of ideal gas and this is not applied for real gas.
So the correct answer is option B.
Explanation of Solution
Assumptions of the kinetic molecular theory:
- Gases consist of tiny particles.
- The volume occupied by the gas molecules is negligible compared to the volume of the gas.
- There is no force of attraction between gas particles.
- The average kinetic energy of gas particles is directly proportional to the absolute temperature.
Among the above assumptions, the assumption that there is no force of attraction between gas particles is responsible for the behavior of ideal gas and this is not applied for real gas.
Reasons for incorrect options:
From the assumptions we see the assumption that there is no force of attraction between gas particles is responsible for the behavior of ideal gas.
So the answer is option B.
That means other options are incorrect.
