Answer 1

Answer: Option (c) is the correct answer.

Step-by-step explanation:

When two objects of different temperature come in contact with each other then heat will flow from hot object to cold object. This process of transfer of heat is known as conduction.

For example, a pan of boiling eggs on a gas burner will have transfer of heat from gas burner to the pan and then heat will flow from water to the eggs.

This process is also a conduction process.

Thus, we can conclude that the path of heat flow will be as follows.

`\text{burning gas} \rightarrow \text{pan} \rightarrow \text{water} \rightarrow \text{eggs}`

Answer 2

The right choice is "burning gas → pan → water → eggs"

Step-by-step explanation:

Heat will flow from the body of higher temperature to the cooler body.

So, heat will firstly flow from burning gas to pan by conduction then to the water in contact with pan then to the egg present inside the water.

So, the right choice is :

"burning gas → pan → water → eggs"
