Question

One end of a copper rod is placed in a flame of a Bunsen burner. Small pieces of wax placed along the rod melt at progressively larger distance from the flame. Heat is transferred through the rod by ________.

1) Convection
2)Radiation
3)Conduction​

Answer 1

3) Conduction

Step-by-step explanation:

• When heat is transferred through a material, it can be referred to as conduction
• The wax on the rod can only melt by the rod only if it is in contact with it

Answer 2

3) Conduction

Conduction is the process of heat transferring from a region of hotter temperature to a region of colder temperature through a material or substance by its atoms or molecules transferring heat energy to each other through collision
