in one to two sentence, explain a similarity and a difference between the particles in liquid water at 100 degrees celsius

Question

and the particles in steam at 100 degrees celsius

Answer 1

Both liquid water at 100 degrees Celsius and steam at 100 degrees Celsius consist of water molecules that are constantly moving. The main difference is that the water molecules in liquid water are tightly packed together, whereas the water molecules in steam are much more spread out and have higher kinetic energy.
