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

The similarity between the particles in liquid water at 100ºC and the particles in steam at 100ºC is that they both consist of water molecules, while the difference is that particles in liquid water are closely packed together with weak intermolecular forces, whereas particles in steam are far apart with stronger intermolecular forces.

You overhear a friend saying, “Plastic is the worst thing that humans have ever invented.”

In four to five sentences, explain whether you agree or disagree with your friend’s statement. Be sure to include facts that show the range of impacts that plastic has on human society and the environment.

At 100ºC, both liquid water and steam consist of individual water molecules. However, in liquid water, the particles are closely packed and can slide past each other, whereas in steam, the particles are far apart and move freely in the gaseous state.

Both the liquid water particles at 100ºC and the steam particles at 100ºC are made up of water molecules. However, the main difference is that the liquid water particles are tightly packed and have strong intermolecular forces, while the steam particles are highly energetic and have weak intermolecular forces.
