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.
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
A real-life example that uses slope is determining how someone's savings account balance has increased over time. When determining the rate at which the account has increased, the account owner is calculating the slope of the line that shows the changes in the account's balance.Full Answer >
Refrigerator compressors and chemical hand warmers are both real-life examples of enthalpy. Both the vaporization of refrigerants in the compressor and the reaction to the iron oxidation in a hand warmer generate a change in heat content under constant pressure.Full Answer >
Diffusion is the spontaneous movement of any type of particle or molecule from an area of high concentration to an area of low concentration, while osmosis is the diffusion of water across a semi-permeable membrane. Osmosis only occurs in liquid. Diffusion mainly occurs in a gaseous state, though it also occurs in liquids.Full Answer >
One of the most common real life examples of a redox reaction is one that is necessary for life itself, in which a cell oxidizes glucose to carbon dioxide and reduces oxygen to water, providing energy through cellular respiration. In plants, the reaction occurs in the opposite direction and uses energy supplied by the sun, according to Reference.com.Full Answer >
