  2. Cloud - Wikipedia

    en.wikipedia.org/wiki/Cloud

    Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases. As a result, the cloud base can vary from a very light to very-dark-gray depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer. High thin tropospheric clouds ...

    the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles; the cloud effective particle size for both liquid and ice, ranging from 0 to 200 μm

  4. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    Hexatic state, a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. Ferroics; Ferroelastic state, a phenomenon in which a material may exhibit a spontaneous strain. Photon molecule: Photons which are connected with each other, attracted by apparent mass while mediating energy transfer.

  5. State of matter - Wikipedia

    en.wikipedia.org/wiki/State_of_matter

    A vapor can exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid). A supercritical fluid (SCF) is a gas whose temperature and pressure are above the critical temperature and critical pressure respectively. In this state, the distinction between liquid and gas disappears.

  6. Water vapor - Wikipedia

    en.wikipedia.org/wiki/Water_vapor

    Whenever a water molecule leaves a surface and diffuses into a surrounding gas, it is said to have evaporated. Each individual water molecule which transitions between a more associated (liquid) and a less associated (vapor/gas) state does so through the absorption or release of kinetic energy. The aggregate measurement of this kinetic energy ...

    Gas Liquid Solid Dispersion medium Gas No such colloids are known. Helium and xenon are known to be immiscible under certain conditions. [13] [14] Liquid aerosol Examples: fog, clouds, condensation, mist, steam, hair sprays: Solid aerosol Examples: smoke, ice cloud, atmospheric particulate matter: Liquid Foam Example: whipped cream, shaving cream

  8. Condensation - Wikipedia

    en.wikipedia.org/wiki/Condensation

    Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle . [ 1 ] It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within ...

  9. Liquid water content - Wikipedia

    en.wikipedia.org/wiki/Liquid_water_content

    Clouds that have low densities, such as cirrus clouds, contain very little water, thus resulting in relatively low liquid water content values of around .03 g/m 3.Clouds that have high densities, like cumulonimbus clouds, have much higher liquid water content values that are around 1-3 g/m 3, as more liquid is present in the same amount of space.
