Question

Is there any change in mass when a substance changes its state? Explain with example.(AS)
​

Answer 1

Answer:

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 shows there is no change in the mass even if a substance changes its state.
