The most commonly observed real life example of osmosis is the pruning of the fingers when they are immersed in water for a lengthy period of time. Other easily observable examples of osmosis include soaking dehydrated fruit and vegetables until they expand, or watching a freshly watered plant absorb water through the soil.Continue Reading
In very simple terms, osmosis is the movement of water across a selectively permeable membrane. The process is driven by a difference in solute concentrations on each side of the membrane. Osmosis occurs in almost all animals cells. Indeed, simply hydrating the body with a refreshing glass of water is a living example of the osmosis process.
The pruning of the extremities after a long bath or a swim is a good example of osmosis because many people assume that the fingers have wrinkled because they have lost water. In fact, fingers prune in water due to osmosis, as the external water around the body is more diluted than the water in the body. The external water essentially attempts to enter the body by attempting to cause equilibrium with it, and pruned fingers are a sign of water absorption as water attempts to enter the body. This also explains why dead animals rise to the surface in bodies of water, as the carcass soaks up water and becomes bloated over time.Learn more about Chemistry
An easy example of a solid, liquid and gas is ice, water and water vapor. Solid, liquid and gas are the three main forms that matter can exist in. Solid water is ice, liquid water is water and gaseous water is water vapor.Full Answer >
Gasoline burning is an example of a chemical change, because this process produces water vapor and carbon dioxide. For something to be categorized as a chemical change, it must form new chemical substances. It also entails making and breaking molecular bonds. Another example is iron rusting, which forms iron oxide.Full Answer >
Dissolving salt in water is an example of a chemical change. The dissolution leads the salt to break into sodium and chlorine ions, so it alters its essential chemical properties. Even though boiling salt water ends up leaving behind a residue of salt, while the salt and water are together, the chemical processes change enough to be viewed as a chemical reaction.Full Answer >
An example of concentration gradient is food dye diffusing in a glass of water. A concentration gradient is the change in concentration in a solution measured over the distance.Full Answer >
