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.
In boiling, bubbles do not form at the bottom and rise to the surface. Evaporation occurs at room temperature and therefore, occurs at a slower rate when compared to boiling. In boiling, there is formation of bubbles as it is a complex physical process and these bubbles are formed on a heated liquid.
