Property 5: Water expands when it freezes. liquid solid Water is the only liquid that becomes less dense when it freezes. Density is the amount of mass per unit volume that an object has. In other words, density is how crowded together the molecules are. Look at the pictures of the molecules in liquid water compared to solid water (ice). Using this information and the terms density and molecule: answer this question: Why can fish survive in a pond during the winter? Add text here

Which statement best fits the following diagram? The purplish dots are sugar molecules and the blue areas are water molecules. On the left side the water molecwles have a concentration of 99.1% and on the right side the water molecules have concentration of 99.9%. 1) The level of fluid on the left will rise because water will move by osmosis through the membrane. 2) The level of the fluid on the left will fall as water moves to the right by osmosis. 3) The level of the water on the left will rise as a result of sugar molecules diffusing through the membrane. 4) The level of the water on the left will fall as sugar molecules diffuse through the membrane.
