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 a cooling process--each molecule lost lowers the energy of the remaining molecules Atmospheric Pressure acts as solid lid to evaporating liquid. Once Evaporation-Condensation Equilibrium is reached, the pressure that the gas exerts over the liquid is the Vapor Pressure of the liquid.
