Assertion Reason Questions on Heat Transfer in Nature
Assertion Reason Questions
Q1. Assertion (A): In solids, heat is transferred mainly by conduction.
Reason (R): In conduction, heat transfer occurs due to the movement of particles from the hot region to the cold region.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: In conduction, particles vibrate and pass heat to neighbouring particles without actual movement.
Difficulty Level: Moderate
Q2. Assertion (A): Air in coastal areas moves from sea to land during daytime, creating a sea breeze.
Reason (R): Water heats up faster than land during the day, causing air above the sea to rise.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Land heats up faster than water, making air over land rise and cool sea air move in.
Difficulty Level: Tough
Q3. Assertion (A): Heat from the Sun reaches Earth mainly by conduction through air particles.
Reason (R): Radiation is the mode of heat transfer that does not require any medium.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (d) A is false, and R is also false.
Explanation: Sun’s heat reaches Earth by radiation, not conduction. Radiation does not require a medium.
Difficulty Level: Moderate to Tough
Q4. Assertion (A): Wearing dark-coloured clothes in winter helps to keep the body warmer.
Reason (R): Dark colours absorb more heat from the surroundings compared to light colours.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (a) Both A and R are true, and R is the correct explanation of A.
Explanation: Dark colours absorb and retain more heat, making them better suited for winters.
Difficulty Level: Moderate
Q5. Assertion (A): Water cycle maintains the balance of water on the Earth.
Reason (R): In the water cycle, water only evaporates and is never replenished.
Options:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, and R is also false.
Answer: (c) A is true, but R is false.
Explanation: Water cycle includes evaporation, condensation, and precipitation, continuously recycling water.
Difficulty Level: Moderate

Frequently Asked Questions (FAQs) on Heat Transfer in Nature Assertion Reason Questions
Q1: What are Assertion-Reason questions in Class 7 Science?
A1: Assertion-Reason questions consist of two statements: an Assertion (A) and a Reason (R). Students must determine whether both statements are true and if the reason correctly explains the assertion.
Q2: How do I answer Assertion-Reason questions correctly?
A2: To answer correctly, follow these steps:
Check if both statements are true.
If both are true, see if the reason logically explains the assertion.
Use the standard answer choices (Both true with explanation, Both true without explanation, A true but R false, A false but R true).
Q3: What is the new Science textbook “Curiosity” for Grade 7 about?
A3: The new textbook “Curiosity” for Grade 7 Science introduces students to the world of scientific exploration and discovery.
