Answer 1

Answer:

Increase in volume of a body on heating is referred to as. "VOLUMETRIC EXPANSION " or "CUBICAL EXPANSION". Consider a metallic body of volume = V1 . Let it's temperature is raised by T. then experimentally "Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T).
