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.
This is why sprays evaporate faster (large surface area), clothes dry faster on windy days (higher velocity of air), you feel hotter on a humid day (your sweat does not evaporate as easily) and you will see more steam from a hot cup of coffee than cold one (higher temperature).
