Case Study Questions on Heat Transfer in Nature

Case Study Question 1:

Passage: Understanding Land and Sea Breeze

While visiting a coastal town, students observed a refreshing breeze during the day and a reverse breeze at night. Their teacher explained that this was due to the uneven heating of land and sea, resulting in convection currents. This phenomenon is an example of heat transfer in nature and helps regulate temperature in coastal areas.

Q1. What causes a sea breeze during the day?
(a) Sea heats faster than land
(b) Land heats faster than sea
(c) The moon pulls air toward the shore
(d) Water evaporates from land
Answer: (b)
Difficulty Level: Easy
Explanation: Land heats up faster during the day, causing warm air to rise and cool sea air to move in.

Q2. At night, which area remains warmer and causes a land breeze?
(a) Land
(b) Sea
(c) Mountains
(d) Desert
Answer: (b)
Difficulty Level: Easy
Explanation: Water cools slowly and retains heat longer, causing warm air over the sea to rise and land air to replace it.

Q3. Which type of heat transfer is responsible for the movement of air in this process?
(a) Conduction
(b) Convection
(c) Radiation
(d) Reflection
Answer: (b)
Difficulty Level: Easy
Explanation: Convection causes warm air to rise and cooler air to move in, forming breezes.

Q4. Which of the following is a result of heat transfer in nature?
(a) Earthquake
(b) Photosynthesis
(c) Land and sea breeze
(d) Formation of clouds
Answer: (c)
Difficulty Level: Moderate
Explanation: Land and sea breezes are caused by temperature differences and heat transfer through convection.

Case Study Question 2

Passage: Modes of Heat Transfer in Daily Life

In a classroom experiment, students heated a metal rod with wax-attached pins and observed that the pins fell one by one starting from the heated end. In another experiment, coloured water in a beaker was heated from below, and the colour started rising and circulating. These demonstrated the different modes of heat transfer: conduction in solids and convection in liquids.

Q1. What mode of heat transfer was demonstrated in the metal rod experiment?
(a) Conduction
(b) Convection
(c) Radiation
(d) Insulation
Answer: (a)
Difficulty Level: Easy
Explanation: Heat passed through the solid metal from the flame, which is conduction.

Q2. What mode of heat transfer caused the coloured water to rise in the beaker?
(a) Radiation
(b) Convection
(c) Conduction
(d) Diffusion
Answer: (b)
Difficulty Level: Moderate
Explanation: Heated water becomes lighter and rises, while cooler water sinks — a convection current.

Q3. Which material is the best conductor of heat among the following?
(a) Plastic
(b) Wood
(c) Copper
(d) Glass
Answer: (c)
Difficulty Level: Easy
Explanation: Copper is a metal and a very good conductor of heat.

Q4. What kind of heat transfer allows us to feel warmth from the sun even though it’s 150 million km away?
(a) Conduction
(b) Convection
(c) Radiation
(d) Expansion
Answer: (c)
Difficulty Level: Moderate
Explanation: Radiation is the only mode that can transfer heat through a vacuum like space.

Case Study Question 3:

Passage: The Warmth of the Bukhari

In the cold Himalayan region, families use a traditional room heater called the bukhari. It has a metal stove that burns wood, a chimney to release smoke, and a flat surface used for cooking. While using the bukhari, Tashi noticed that the area near the stove was warmer, even if he wasn’t touching it. His teacher explained that the bukhari demonstrates all three modes of heat transfer – conduction, convection, and radiation.

Q1. Which type of heat transfer allows you to feel warmth from the bukhari without touching it?
(a) Conduction
(b) Convection
(c) Radiation
(d) Evaporation

Answer: (c)
Difficulty Level: Moderate
Explanation: Radiation transfers heat through air or vacuum without needing direct contact.

Q2. What role does the chimney in the bukhari play?
(a) It produces more heat
(b) It distributes smoke evenly
(c) It removes smoke from the room
(d) It cools down the bukhari

Answer: (c)
Difficulty Level: Easy
Explanation: The chimney removes smoke and gases produced during combustion, ensuring proper ventilation.

Q3. Why is the top surface of the bukhari useful for cooking?
(a) It receives heat through convection from air
(b) It reflects heat onto utensils
(c) It gets heated through conduction
(d) It absorbs heat through radiation

Answer: (c)
Difficulty Level: Moderate
Explanation: The metal surface conducts heat from the fire inside to the utensil placed above.

Q4. How does warm air spread throughout the room from the bukhari?
(a) Through reflection
(b) Through evaporation
(c) Through radiation
(d) Through convection

Answer: (d)
Difficulty Level: Easy
Explanation: Heated air rises and cooler air moves in to replace it, creating a convection current.

We hope the given case study questions for Heat Transfer in Nature Class 7 helps you in your learning.
