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 occurs on the surface of liquid and it is a vaporization of liquid. It is a state of transition from liquid to gaseous state. The process occurs slowly and cannot be seen as well. It occurs when there is exposure of water to air and water molecules change into vapor and these vapors rise up and form clouds.
