volume. When a material changes phases, it changes in density in a predictable way as the amount of material stays the same but the molecules get farther apart or closer together. Water has solid and liquid states that do not follow these predictions of density in the phases of matter.

What does that mean about the densities of the phases of water?

The solid state is the most dense, followed by the liquid state, then the gas state.
The solid state is more dense than the liquid state.
The liquid state is more dense than the solid state.
The gas state is the most dense, followed by the liquid state, then the solid state.

Will give if correct read the passage first of all, if someone says your dream is impossible, they’re wrong. you can’t prove that something is impossible-all you know is that [it] hasn’t been done yet. people said no one could scale mount everest, but in 1953, sir edmund hilary and tenzing norgay gazed down upon the world from its summit. people said that man could not fly, but in 1903, orville and wilbur wright made the first sustained powered flight in a heavier-than-air machine. people said, “okay, we admit that someone could climb mount everest, and we admit that man has learned to fly, but no one will ever, ever walk on the face of the moon.” if we can send three men a quarter of a million miles away and bring them home safely, is there any great task we cannot accomplish? which identifies the textual evidence that best supports the claim: the authors purpose is to persuade? a: the author shares historical information about the wright brothers. b: the author states that men have walked the moon. c: the author states that others who think your dreams are impossible are wrong. d: the author wants to know what tasks we cannot accomplish.
