1.Who discovered or names phases and phase changes?

2.Is there water vapor in the air? Why don't we see it?

3.What does liquid methane look like?

4.Can all substances change phase? Explain.

Answer 1

Answer:

1. Josiah Willard Gibbs.

2. Gaseous water, or water vapor, isn't something you can see, but it's part of the air around you. Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation.

3. Its like a yellow,

It would feel as if you were made of stone. On the surface of the lake, the liquid methane would appear completely clear, but you still wouldn't be able to see too deep due to the dark rock and thick atmosphere on the moon.

4. Substances can change phase — often because of a temperature change. At low temperatures, most substances are solid; as the temperature increases, they become liquid; at higher temperatures still, they become gaseous.
