Question

2. Mention a condition that must be satisfied for heat transfer by conduction

3. What determines the direction of flow of heat between two objects in contact ?​

Answer 1

Answer:

Ans.2-For conduction of heat from one object to other, it must satisfy two conditions. Firstly, the objects should be in contact with each other. Secondly, they should have different temperature. But in this case, only the first condition is satisfied; hence, the heat energy will not be transferred.

Ans.3-The difference in temperature of the bodies determines the direction of flow of heat. Heat flows from a body at higher temperature to one at a lower temperature.

Answer 2

Answer:

for the second question the condition can be that both the substance must be in contact with each other

for the third question the answer can the temperature , the substance with higher temperature will transfer its heat towards the cooler one so the temperature different determins the flow of heat
