Both liquid water and steam at 100ºC are composed of water molecules in motion, but the molecules in liquid water are tightly packed and held together by intermolecular forces, whereas the molecules in steam are more dispersed and move independently due to the absence of these forces.fhdndh

Answer 1

That's a great summary of the differences between liquid water and steam at 100ºC. In liquid water, the molecules are indeed closely packed and interact with each other through intermolecular forces, such as hydrogen bonds. These forces keep the water molecules in a relatively fixed arrangement, allowing them to flow but not to move freely.

In contrast, when water transitions to steam (gas phase), the heat energy provided during the phase change allows the water molecules to gain enough kinetic energy to overcome these intermolecular forces. As a result, the steam molecules are much farther apart and move independently, leading to a much lower density compared to liquid water.

This difference in molecular arrangement and behavior explains many properties of water in its different states, including differences in density, viscosity, and heat capacity. If you have any specific questions or need further information on this topic, feel free to ask!

Answer 3

Sure!

Liquid water and steam at 100ºC both consist of water molecules in motion, but their arrangements differ significantly. In liquid water, molecules are tightly packed and held together by intermolecular forces, allowing them to flow but not move freely. In steam, however, the molecules have enough energy to overcome these forces, becoming more dispersed and moving independently. This difference in arrangement leads to variations in properties like density and viscosity between the two states.
