GK QUESTION#3341
Consider the following statements about the properties of an ideal gas:
1. The volume of ideal gas molecules is negligible compared to the total volume of the container.
2. Collisions between ideal gas molecules are perfectly elastic.
3. Strong attractive forces exist between the ideal gas molecules.
Which of the above statements is/are correct?
Show Answer
Answer
A. 1 and 2 only
Show Explanation
Explanation
In the ideal-gas model, particles occupy negligible volume compared with the container and their collisions conserve kinetic energy. Interparticle attractions and repulsions are neglected except for the idealised collisions. Statements 1 and 2 are correct; strong attractive forces are not an ideal-gas assumption.
