How is cubical expansion calculated? “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). What is an example of anomalous Behaviour […]
