Answer 2

2. The particles will have more space between them as steam, but they will be moving at the same speed in both states.

Answer 3

The correct response to the question about the similarities and differences between water at 100°C and steam at 100°C is:

• The particles will have more space between them and will be moving at higher speeds as steam.

In steam, the particles are farther apart compared to those in liquid water, and steam particles generally have higher kinetic energy, resulting in higher speeds. Thus, the statement "they will be moving at the same speed in both states" is not correct.
