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.
Lesson Summary. Evaporation is a process during which water in a liquid state changes to gas or vapor. Water starts evaporating at 32 degrees F (0 degrees C), but it happens very slowly. The higher the temperature, the higher the rate of evaporation; however, evaporation cannot occur if there is no water available.
