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.
Evaporation is the change of water from a liquid to a gas. Water is continuously evaporating from the surface of the Earth, literally pumping more and more water vapor into the atmosphere. Averaged across the entire Earth, water evaporates from the surface at a rate of about 3 millimeters per day (about 1/8 of an inch). Over the tropical oceans, the value is much larger; over cold surfaces, it is much lower; and over deserts it is almost zero, since there is little or no water to evaporate.
