Assertion Reason Questions

Q. 1. Assertion (A): Water vapour condenses into liquid water when cooled.
Reason (R): Evaporation involves the absorption of heat.
(a) Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true, but reason (R) is false.
(d) Assertion (A) is false, but reason (R) is true.

Ans. Option (b) is correct.
Explanation: Water vapour condenses into liquid water when cooled. This is true because condensation occurs when water vapour loses heat and turns back into liquid. Evaporation involves the absorption of heat. This is also true because evaporation requires heat to change liquid water into water vapour. However, evaporation and condensation are opposite processes, and the absorption of heat during evaporation is not directly related to the cooling and condensation of water vapour.

Q. 2. Assertion (A): Evaporation increases with higher temperatures.
Reason (R): Evaporation is not affected by wind conditions.
(a) Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true, but reason (R) is false.
(d) Assertion (A) is false, but reason (R) is true.

Ans. Option (c) is correct.
Explanation: Higher temperatures increase the rate of evaporation as heat provides energy for water molecules to escape. However, wind conditions do affect evaporation by moving the evaporated water away, thus speeding up the process. Hence, the assertion is correct, but the reason provided is not.

What is Assertion Reason Question for Class 6 Science?

Assertion-Reason Questions are a type of objective question where students are given two statements:

1. Assertion (A) – A factual or conceptual statement related to the topic.
2. Reason (R) – An explanation or justification for the assertion.

Students need to evaluate both statements and select the correct option based on their relationship.

Answering Format

Typically, the answer choices are:

1. Both A and R are true, and R correctly explains A.
2. Both A and R are true, but R does not explain A.
3. A is true, but R is false.
4. A is false, but R is true.

Best Ways to Prepare for Assertion Reason Questions

Assertion-Reason (A-R) questions test conceptual understanding and logical reasoning. Here’s how you can effectively prepare for them:

1. Strengthen Conceptual Understanding

• Read NCERT and reference books thoroughly.
• Understand key concepts, definitions, and principles in each chapter.
• Use mind maps and flowcharts for quick revision.

2. Focus on Cause-Effect Relationships

• Identify if the Reason correctly explains the Assertion.
• Ask yourself: Does R provide a valid explanation for A, or is it just another true statement?
• Practice linking concepts to real-life examples.

3. Practice with Assertion-Reason Questions

• Solve chapter-wise A-R questions from textbooks, sample papers, and previous years’ papers.
• Attempt mock tests and quizzes to improve accuracy.

4. Use the Elimination Technique

• If either A or R is false, eliminate options 1 and 2.
• If both A and R are true, check if R correctly explains A.

5. Improve Logical Reasoning Skills

• Understand different types of reasoning (scientific, mathematical, logical).
• Read explanations carefully and analyze the connection between statements.

6. Regular Revision

• Revise key concepts regularly to strengthen memory.
• Create short notes or flashcards for quick recall.
