Question

is ther any change in mass when a substance its state? example?

Answer 1

When a substance changes its state ,there will not be any change in the mass of substance . For example , if we change 100 grams of water (liquid) to ice(solid) , the mass of ice will be same i.e., 100 grams . This showsthere is no change in the mass even if a substance changes its state

Hope this will help you and
