But that's not necessarily the case. If you start with water and you make it colder and colder and colder to zero degrees, you're essentially taking heat out of the water. You can have zero degree water and it hasn't turned into ice yet. And likewise, you could have 100 degree water that hasn't turned into steam yeat. You have to add more energy.

A graph of the variation of solubility with temperature is known as a solubility curve, and it can be used to predict the solubility of the solid at any temperature. Teacher Summary The masses that will dissolve at a given temperature will vary, depending on how rapidly the hot solution is filtered. The magnitude of one degree Celsius is the same as one K. The only difference between those two scales is the zero point. Part of the reason for this quick review of temperature is because we are now going to begin studying the emission of light by different bodies, and all objects with temperatures above absolute zero give off light.

Let's compare sugar in water (H 2 O) to sand in water. Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sand-water is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution. Can anything be in a Solution ...
