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.
For example, on a hot summer's day if you sprinkle water on your skin it will cool your skin as you evaporate. That's an example of refrigeration! Water can't be used in freezer though, because it evaporates at too high a temperature. But some liquids evaporate at very low temperatures. For example Isobutane (becoming more common in domestic freezers) evaporates at very low temperatures.
