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.
So, as the fast molecules escape, the temperature of remaining water drops. That's why evaporation cools. See Figure 2, top drawing. Water boils when evaporation occurs throughout the pot â not just on the surface â and forms bubbles that are buoyed to the top where they escape.
