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)

Answer 1

The similarity between the particles in liquid water and steam at 100ºC is that both have particles that are moving and have enough energy to overcome forces of attraction, leading to a more disordered arrangement. However, the difference is that in liquid water, the particles are closer together and have a higher density, while in steam, the particles are farther apart and have a lower density.

Answer 2

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.
