At 100ºC, both liquid water and steam consist of water molecules. However, in liquid water, the water molecules are closely packed and moving more slowly, while in steam, the water molecules are spread out and moving rapidly.

I partially agree with my friend's statement that plastic is one of the worst inventions by humans. On one hand, plastic has numerous benefits such as being lightweight, durable, and versatile, making it a crucial material in various industries. However, the environmental impacts of plastic cannot be ignored. Plastic waste is a major contributor to pollution, especially in the oceans, where it harms marine life and ecosystems. Additionally, plastic takes hundreds of years to degrade, leading to long-lasting environmental damage. Therefore, while plastic has its uses, its negative environmental consequences cannot be ignored, highlighting the need for better waste management and reduction of plastic consumption.
