  2. Aquaplaning - Wikipedia

    en.wikipedia.org/wiki/Aquaplaning

    A diagram of an aquaplaning tire Two vehicles aquaplaning through large puddles on the road's surface. Aquaplaning or hydroplaning by the tires of a road vehicle, aircraft or other wheeled vehicle occurs when a layer of water builds between the wheels of the vehicle and the road surface, leading to a loss of traction that prevents the vehicle from responding to control inputs.

  3. Water potential - Wikipedia

    en.wikipedia.org/wiki/Water_potential

    Pressure potential increases as water enters a cell. As water passes through the cell wall and cell membrane, it increases the total amount of water present inside the cell, which exerts an outward pressure that is opposed by the structural rigidity of the cell wall. By creating this pressure, the plant can maintain turgor, which allows the ...

  4. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    When in a hypotonic solution, water flows into the membrane and increases the cell's volume, while in an isotonic solution, water flows in and out of the cell at an equal rate. [4] Turgidity is the point at which the cell's membrane pushes against the cell wall, which is when turgor pressure is high. When the cell has low turgor pressure, it is ...

  5. Suction pressure - Wikipedia

    en.wikipedia.org/wiki/Suction_pressure

    Turgid cells cannot absorb any more water. Thus, with reference to plant cells, the DPD can be described as the actual thirst of a cell for water [1] and can be expressed as : = Thus it is DPD that tends to equate and represents the water-absorbing ability of a cell, it is also called suction force (SF) or suction pressure (SP). The actual ...

  6. Kugel fountain - Wikipedia

    en.wikipedia.org/wiki/Kugel_fountain

    (C) Water is pumped back in an endless loop. (D) Pump. (E) Ball can easily be moved by hand. A kugel fountain (also called a floating sphere fountain or by the pleonasmic name kugel ball) is a water feature or sculpture where a sphere sits in a fitted hollow in a pedestal, and is supported by aquaplaning on a thin film of water.

  7. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    A typical phase diagram.The solid green line applies to most substances; the dashed green line gives the anomalous behavior of water. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. [1]

  8. Monolayer - Wikipedia

    en.wikipedia.org/wiki/Monolayer

    It is analogous with a 3D process in which pressure varies with volume. A variety of bidimensional phases can be detected, each separated by a phase transition. During the phase transition, the surface pressure doesn't change, but the area does, just like during normal phase transitions volume changes but pressure doesn't.

  9. Contractile vacuole - Wikipedia

    en.wikipedia.org/wiki/Contractile_vacuole

    The stage in which water flows into the CV is called diastole. The contraction of the contractile vacuole and the expulsion of water out of the cell is called systole. Water always flows first from outside the cell into the cytoplasm, and is only then moved from the cytoplasm into the contractile vacuole for expulsion. Species that possess a ...
