Answer:
Thermal conduction
Explanation:
Heat can be transferred from one body to another by three processes i.e.
1. Radiation
2. Conduction
3. Convection
In this case, a chef places sugar crystals in a cooking pan. He turns on the burner under the pan. In a few minutes, the sugar begins to melt. The process responsible for transferring heat from the burner into the sugar is thermal conduction.
It is a process of transferring heat when two bodies are in contact with each other. The heat conduction depends on four factors i.e. area of cross section, temperature gradient, path length and properties of materials.
Here, heat is moving to the pan and then it is absorbed from the pan to the sugar. Hence, the correct option is (c) " conduction ".
