Both the particles in liquid water and steam at 100°C are in constant motion and have higher kinetic energy compared to particles in colder states, however, the particles in steam have a higher average kinetic energy and are more widely spaced apart compared to the particles in liquid water. make this like a 8th grader wrote it
When water gets really hot, it turns into steam. The particles in both liquid water and steam are always moving and have more energy when they are hotter. But in steam, the particles are even more energetic and spread out more than in liquid water. It's like they are running around faster and further apart. So, steam has more energy and more space between the particles than liquid water.
