  2. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    When the molecules of the liquid collide, they transfer energy to each other based on how they collide. When a molecule near the surface absorbs enough energy to overcome the vapor pressure , it will escape and enter the surrounding air as a gas. [ 3 ]

  3. Particulate pollution - Wikipedia

    en.wikipedia.org/wiki/Particulate_pollution

    Atmospheric particulate matter, also known as particulate matter, or PM, describes solids and/or liquid particles suspended in a gas, most commonly the Earth's atmosphere. [1] Particles in the atmosphere can be divided into two types, depending on the way they are emitted. Primary particles, such as mineral dust, are emitted into the atmosphere ...

  4. Upstream contamination - Wikipedia

    en.wikipedia.org/wiki/Upstream_contamination

    Particles can climb up the falling water while preparing a mate beverage. Upstream contamination by floating particles is a counterintuitive phenomenon in fluid dynamics. When pouring water from a higher container to a lower one, particles floating in the latter can climb upstream into the upper container.

    en.wikipedia.org/wiki/Collision_theory

    The rate for a bimolecular gas-phase reaction, A + B → product, predicted by collision theory is [6] = = ⁡ ()where: k is the rate constant in units of (number of molecules) −1 ⋅s −1 ⋅m 3.

  6. Ostwald ripening - Wikipedia

    en.wikipedia.org/wiki/Ostwald_ripening

    Dissolution of small crystals or sol particles and the redeposition of the dissolved species on the surfaces of larger crystals or sol particles was first described by Wilhelm Ostwald in 1896. [ 4 ] [ 5 ] For colloidal systems, Ostwald ripening is also found in water-in-oil emulsions , while flocculation is found in oil-in-water emulsions.

    The body of mold consists of a thread-like root that invades the food, a stalk that rises above the food and may not be visible to the naked eye, and spores that form at the end of the stalks ...

  9. Atmospheric escape - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_escape

    One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.
