Question:-
Which condition must exist in order for conduction to occur between two substances?
Answer:-
Conditions :-
- Temperature difference :- There must be a temperature difference between two substance for the conduction which is a type of heat flow to occur . temperature difference can be maintained artificially by using energy or can be natural without any expenditure of energy by humans
- Contact Between them :- There must be a point of contact between two substance because conduction is the movement of heat energy from hotter body to lower body through the point of contact as conduction cannot occur if two bodies are not in contact or kept far away
