Question

Which of the following is NOT an assumption of the kinetic theory of ideal gases?

SUBHANI · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Kinetic Theory of Ideal Gases
 **Related Topics**: Ideal gas law, gas properties, intermolecular forces
 **Prerequisites**: Understanding of basic gas behavior and molecular motion.
## SOLUTION PATHWAY
**Given Information**:
	The question asks to identify a statement that is NOT an assumption of the kinetic theory of ideal gases.
**Method & Steps**:
 1. Review the assumptions of the kinetic theory of ideal gases.
  Reasoning: The kinetic theory of ideal gases is based on several simplifying assumptions about the behavior of gas molecules.
  Formula/Rule:  None directly applicable, but understanding the assumptions is key.
 2. Analyze each option against the assumptions.
  Working: Let's examine each option:
		 a) Gas molecules are in constant random motion. (TRUE - This is a fundamental assumption)
		 b) Collisions between gas molecules are perfectly elastic. (TRUE -  No energy loss during collisions)
		 c) Gas molecules have significant volume compared to the container. (FALSE - Ideal gas theory assumes negligible volume of gas molecules compared to the container volume)
		 d) There are no intermolecular forces between gas molecules. (TRUE -  No attractive or repulsive forces between molecules)
 3. Identify the statement that contradicts the assumptions.
  Result: Option C is the only statement that is NOT an assumption of the kinetic theory of ideal gases.  Ideal gases are assumed to have negligible volume.
  Verification: The other options directly align with the assumptions of the kinetic theory of ideal gases.
 ## OPTION ANALYSIS
A ✓: Gas molecules are in constant random motion. This is a core assumption of the kinetic theory.
B :x: Collisions between gas molecules are perfectly elastic.  This is another fundamental assumption.
C :x: Gas molecules have significant volume compared to the container. This is incorrect; ideal gas molecules are assumed to have negligible volume.
D :x: There are no intermolecular forces between gas molecules. This is a crucial assumption for ideal gases.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing ideal gases with real gases: Real gases do exhibit intermolecular forces and have finite molecular volumes.
  2.Overlooking the significance of assumptions:  Understanding the limitations imposed by these assumptions is crucial for applying the ideal gas law appropriately.
 **Quick Tips**:
  1.Memorize the key assumptions of the kinetic theory of ideal gases.
  2.Remember that ideal gases are a model; real gases deviate from ideal behavior under certain conditions.
