Hi
Condensation of stem is a chemical change or physical change
Condensation of steam is a physical change. Only the physical state of matter is changed in the process. Water can be heated again to form steam. In condensation, the gas turns into a liquid. The molecules of the gas do not change when they turn into the liquid
Some of the learners also asked: What kind of change is observed when we collect the chalk dust and convert it into chalk piece
