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)
A similarity between the particles in liquid water at 100ºC and the particles in steam at 100ºC is that both are composed of water molecules. A difference is that the particles in liquid water are held together by hydrogen bonds, while the particles in steam are not held together and are instead dispersed in the air.
dead wrong.
A similarity between the particles in liquid water at 100ºC and steam at 100ºC is that they both consist of water molecules. A difference is that the particles in liquid water are closely packed and have less energy, while the particles in steam are spread out and have more energy.
A similarity between particles in liquid water at 100ºC and particles in steam at 100ºC is that both consist of H2O molecules. A difference is that the particles in liquid water are closely packed and have higher intermolecular forces, while the particles in steam have more kinetic energy and are more spaced apart.
To understand this, it is important to have knowledge of the physical properties of water and the behavior of its particles at different temperatures. At 100ºC, water undergoes a phase change from a liquid (water) to a gas (steam). This phase change is driven by an increase in temperature, which provides energy to the water molecules, causing them to gain kinetic energy and move faster.
In the liquid water at 100ºC, the molecules are closely packed and have strong intermolecular forces. These forces are responsible for the fluidity and cohesion of the liquid. However, the increased temperature allows individual water molecules to gain enough energy to overcome these intermolecular forces and transition into a gas phase.
In steam at 100ºC, the water molecules have a higher kinetic energy due to the increased temperature. This results in the water molecules moving rapidly and being more spaced apart compared to the liquid water. The increased kinetic energy also weakens the intermolecular forces, leading to a less cohesive and more freely moving gas.
Understanding the basic concepts of phase changes, temperature, kinetic energy, intermolecular forces, and the behavior of water molecules helps in differentiating the particles in liquid water at 100ºC from those in steam at 100ºC and identifying both the similarity and difference between them.
