Examples of diffusion include the dispersion of tea in hot water and smoke from a lit cigarette spreading in the air. Carbon dioxide bubbles diffusing from an opened bottle of soda cause the soda to become flat as it loses its carbonation.
The human body exhibits diffusion in digestion by transfer of oxygen from the lungs into the blood and from the blood cells into the muscles. It also occurs during pregnancy, as food and oxygen reach the fetus from the mother’s body.
When pouring a cup of hot liquid, such as coffee, the heat diffuses and heats the cup. A sugar cube placed in a liquid dissolves and diffuses throughout the liquid, sweetening it evenly without stirring. Helium balloons exhibit diffusion, deflating as helium is slowly lost from the balloon. The reason you smell perfume on another person is because it diffuses into the surrounding air.
Watering your plants diffuses the water into them so the leaves do not wilt. Leaves diffuse carbon dioxide from air pockets between the mesophyll cells to transfer it to the chloroplast.
Ocean currents exhibit diffusion in meteorology by diffusing warm waters around the equator. In areas where moist warm air rises within cold air, it creates water vapor that leads to rainstorms.Learn More
A chromium atom, which is a transition element, has six unpaired electrons. In its atomic structure, three unpaired electrons are used for bonding with other elements while the remaining three are involved in changing the levels of energy through absorption of energy from the white light.Full Answer >
Mentos makes soda fizz due to the Mentos breaking the bonds in water molecules and encouraging the growth of more carbon dioxide gas, which is used to carbonate sodas. This is due to a combination of a rough surface area, the density of Mentos candies and their coating.Full Answer >
Hydrogen is found in many places including in gas planets, stars and in water. Hydrogen is one of the two elements found in water, which is created with two hydrogen atoms that have bonded to one oxygen atom.Full Answer >
A pure metal is a substance that contains atoms of only one type of metallic element, such as aluminum, gold, copper, lead or zinc. Most metals very rarely, if ever, appear in their pure form in nature and instead must be extracted from a metal ore.Full Answer >
