Answer 1

Both liquid water at 100ºC and steam at 100ºC consist of water molecules (H₂O) that are the same in terms of chemical composition. However, the key difference lies in their arrangement and energy: in liquid water, the molecules are closely packed and have lower kinetic energy, while in steam, the molecules are widely spaced and possess higher kinetic energy, resulting in a gaseous state.
