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.
on a warm, sunny day, water in a glass of water seems to slowly disappear. This is because the energy from the sun is heating the water up and turning the liquid water into water vapor.This process is called evaporation. When the water evaporates, it becomes an invisible gas in the atmosphere. Evaporation takes place especially in the ocens and lakes where there is a lot of water.
