Question
14. Under certain conditions, different gases behave in a similar manner. This approximation is the basis for what is described as an ideal gas. All of the following are descriptions of the behavior of ideal gases EXCEPT
A. In an ideal gas, polar molecules sometimes travel together as a pair or in a small group as droplets.
B. In an ideal gas, molecules are constantly moving in random directions.
C. In an ideal gas, molecules do not attract or repel each other.
D. In an ideal gas, when molecules collide with other molecules, they bounce off and change direction.
E. In an ideal gas, the molecules move in a straight line path until they collide.
A. In an ideal gas, polar molecules sometimes travel together as a pair or in a small group as droplets.
B. In an ideal gas, molecules are constantly moving in random directions.
C. In an ideal gas, molecules do not attract or repel each other.
D. In an ideal gas, when molecules collide with other molecules, they bounce off and change direction.
E. In an ideal gas, the molecules move in a straight line path until they collide.
Explanation / Answer
The answer is:
A. In an ideal gas, polar molecules sometimes travel together as a pair or in a small group as droplets.
Note that in an ideal gas, there are NO intermolecular interactions
=> statement A is incorrect
