Science 8 Q1 / Properties of Matter

In one to two sentences, explain a similarity and a difference between the particles in liquid water at 100ºC and the particles in steam at 100ºC.(2 points)

Both liquid water at 100ºC and steam at 100ºC are made up of particles that can move and flow, but the particles in liquid water are closer together and have weaker intermolecular forces compared to the particles in steam.

The similarity between the particles in liquid water at 100ºC and steam at 100ºC is that both consist of H2O molecules. The difference is that the particles in liquid water are closely packed and have lower kinetic energy compared to the particles in steam which are far apart and have higher kinetic energy.
