Question

Name the predominent modes of heat transfer through which a frying pan:
1. gets heated when kept on a flame;
2. cools down when taken away from the flame.

• A. 1- Convection, 2- Radiation
• B. 1- Both conduction and convection, 2- Radiation
• C. 1- Conduction, 2- Radiation
• D. 1- Radiation, 2- Conduction

Answer 1

The correct option is C 1- Conduction, 2- Radiation


When a frying pan is kept on the flame of a gas stove, its constituent particles start vibrating around their mean positions. They transfer heat energy from one to another. Thus, in this way, the body of the frying pan gets heated through conduction.

Whereas, when the frying pan is taken away from the flame, it loses heat to the atmosphere in all directions through radiation.
