Question

Which of these will expand the most on heating?​

Answer 1

Answer:

iron will expand on heating but here if you have more option give here I will tell u

Answer 2

Answer:On heating, gases expand the most. Because the molecules of gases are not bound to each other, the vibration of molecules increases when gases are heated. This increases the average distance between the molecules, resulting in their expansion.

Explanation:r. gas will expand more when heated to the same temperature as its molecules are not packed where as solid molecules are packed and liquid molecules are more packed as compared to gas.
