  2. Mpemba effect - Wikipedia

    en.wikipedia.org/wiki/Mpemba_effect

    Higher convection in the warmer water may also spread ice crystals around faster. [23] Frost: Frost has insulating effects. The lower temperature water will tend to freeze from the top, reducing further heat loss by radiation and air convection, while the warmer water will tend to freeze from the bottom and sides because of water convection.

  3. Evaporation - Wikipedia

    en.wikipedia.org/wiki/Evaporation

    The evaporation will continue until an equilibrium is reached when the evaporation of the liquid is equal to its condensation. In an enclosed environment, a liquid will evaporate until the surrounding air is saturated. Evaporation is an essential part of the water cycle. The sun (solar energy) drives evaporation of water from oceans, lakes ...

  4. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. [1]

  5. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    This energy heats water in the ocean and seas. Water evaporates as water vapor into the air. Some ice and snow sublimates directly into water vapor. Evapotranspiration is water transpired from plants and evaporated from the soil. The water molecule H 2 O has smaller molecular mass than the major components of the atmosphere, nitrogen (N 2) and ...

  6. Latent heat - Wikipedia

    en.wikipedia.org/wiki/Latent_heat

    If the vapor then condenses to a liquid on a surface, then the vapor's latent energy absorbed during evaporation is released as the liquid's sensible heat onto the surface. The large value of the enthalpy of condensation of water vapor is the reason that steam is a far more effective heating medium than boiling water, and is more hazardous.

  7. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    The molecules of water are constantly moving concerning each other, and the hydrogen bonds are continually breaking and reforming at timescales faster than 200 femtoseconds (2 × 10 −13 seconds). [27] However, these bonds are strong enough to create many of the peculiar properties of water, some of which make it integral to life.

  9. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    The surface tension of the water allows the droplet to stay liquid well below its normal freezing point. When this happens, it is now supercooled liquid water. The Bergeron process relies on super cooled liquid water (SLW) interacting with ice nuclei to form larger particles. If there are few ice nuclei compared to the amount of SLW, droplets ...
