Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
The difference between these two questions is that one has a scientific answer for that question. The one that says, " Can dogs identify colors?" is scientific because it can be answered scientifically but the one that says, "Are dogs better pets than cats?" cannot be answered scientifically.
~Hope that this makes since and helps
Try researching the discovery of microscopes and their impact on scientific discoveries, including cells!!!

a. predicting weather patterns</span>. Scientific models are used in making predictions. One way to do this is by analyzing big chunks of data from the past, and see if it can predict the present with accuracy. Computers are often used to create this models because of the huge amount of data that need to be manipulated.
