Experiment 1: floating ice for this experiment, you will need a permanent marker, a translucent plastic cup, water, and ice. place a few ice cubes in the cup, and add water until the ice cubes float (that is, they don’t touch the bottom). mark the water level on the outside of the cup with the marker, and label this mark so that later you will know it was the initial water level. as the ice melts, what do you expect to happen to the water level in the cup? html editor keyboard shortcuts

Yasmin's teacher asks her to make a supersaturated saline solution. her teacher tells her that the solubility of the salt is 360 g/l at room temperature (25 °c). how can yasmin make a supersaturated saline solution? she can add 380 g of salt to 1 l of hot water (75 °c) and stir until all the salt dissolves. then, she can carefully cool the solution to room temperature (25 °c). she can add 360 g of salt to 1 l of room temperature water (25 °c) and stir the solution until all the salt dissolves. she can add 380 g of salt to 1 l of cold water (5 °c) and stir the solution until most of the salt dissolves. then, she can carefully heat the solution to room temperature (25 °c). she can add 380 g of salt to 1 l of room temperature water (25 °c) and let the solution sit for 24 hours, so the salt dissolves.
