Question:
In which of the following process, convection does not take place primarily?
In which of the following process, convection does not take place primarily?
Show Hint
Heating by filament (as in bulbs) occurs mainly by radiation, not convection.
Updated On: Apr 16, 2026
- Sea and land breeze
- Boiling of water
- Warming of glass bulb due to filament
- Heating air around furnace
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Modes of heat transfer:
• Conduction (in solids)
• Convection (in fluids)
• Radiation (no medium required)
Step 1:Analyze each option.
• (A) Sea and land breeze → Convection (air movement)
• (B) Boiling of water → Convection (liquid currents)
• (D) Heating air around furnace → Convection
Step 2:Remaining option.
• (C) Warming of glass bulb due to filament → mainly radiation Conclusion : C
