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.
Larger distances between particles weakens the forces of attraction between. them. When the forces of attraction ar e weak enough, the distance between the. particles increases markedly and the phase changes. As a result, a solid melts. and a liquid evaporates. The reverse happens when a substance cools. As the. particles slow down and the collisions weaken, the particles move closer.
