| 2. Convection | (b) Transfer of heat through the movement of liquids and gases. |
| 3. Radiation | (c) Heat transfer takes place between objects by direct contact. |
Select the correct answer using the code given below:
The correct option is B 1-c, 2-b, 3-a
Explanation:
Conduction: In conduction, heat transfer takes place between objects by direct contact. The heat transfer takes place due to the difference in temperature. The heat transfer in conduction is slow. The heat transfer occurs through a heated solid object.
Convection: In convection, the heat transfer takes place through the movement of liquids and gases. The heat transfer occurs due to the difference in density. The heat transfer in convection is faster and occurs through intermediate objects. For example, heat transfer between air and water.
Radiation: In radiation, heat transfer occurs through electromagnetic waves without involving particles. The heat transfer occurs in all objects with a temperature greater than 0 K.The heat transfer in radiation is the fastest.
