WebFeb 14, 2024 · Salt water is more dense than fresh water Salt water has more stuff in it than fresh water. That stuff would be the salt, which makes the mass of water greater, without … WebThere is a density difference that initially causes salt water and fresh to layer. That means that after layering, the fresh water must diffuse into the salt water, taking time to do so. Eventually they equalize. Mixing would be faster, but difusion is the only means because of layering due to density difference.

Webdense that freshwater. The density of the water will affect the buoyancy of objects in the water. • Fill one container with freshwater and one with saltwater. Place an egg in freshwater and then in saltwater. The egg should sink in the freshwater and float in the salt water. Have students guess which water the egg sank in and which it floated ... memory testing for the elderly

3.2 The density of fresh water and seawater - The oceans

WebThe answer is just one word-salt. When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt. Because objects float … Weba) Fresh water would be harmful to many salt water species. b) Because fresh water floats on top of salt water, organisms at the bottom might not be affected. c) Shallow areas are more likely to be mixed and will be different than deep areas, where fresh water is less likely to affect life at the bottom. WebWhen fresh water at 3.97 °C (Figure 4) is cooled the density will decrease. You know from the lake (Figure 5) that ice (i.e. solid water) is less dense and floats. But cooling a liquid usually packs the molecules more closely, … memory test in windows
