Name the mode of heat transfer shown by the diagram. An iron ball at 40 0 C
is dropped in a mug containing water at 40 0 C. In which direction does the
heat flow? Give reason.
Answers
Answer:-
Because, not flow from iron ball to water or from water to iron ball.
Explanation:-
Given: Temperature of iron ball= 40°C
Temperature of water in mug = 40°C
Solution: As the iron ball and the water in the mug has the same temperature, so there will be no heat flow from ball to the water or vice versa.
As, heat flow is the result of the temperature difference.

Answer:
bro this mode of heat transfer is called conduction of heat .
Explanation:
see matter is made up of tiny particles called molecules. These molecules are never still. they are in constant motion . but however molecules in solid are tightly packed and are unable to move around freely. however they vibrate around fixed point. heat causes the particles to vibrate faster in contact with the source of heat . these particles bump with each other and transfer energy to neighbouring slow moving particles , which are further away from the source of heat . in this way heat gets transfered from one particle to other .
