The standard deviation is determined by first calculating the mean, then taking the difference of each control result from the mean, squaring that difference, dividing by n-1, then taking the square root.
The higher the heat level is th â¦ e faster the liquids evaporate. But if you leave something outside like syrup for sometime, it will take much more longer to evaporate since syrup has a substance so much thicker than water.
In general, the lighter a compound is (in terms of molecular weight), the more quickly it will evaporate. If you were to obtain liquid helium and then quickly remove it from its container, you would see it vanish quite quickly.
