  2. Color of water - Wikipedia

    en.wikipedia.org/wiki/Color_of_water

    The color of a water sample can be reported as: Apparent color is the color of a body of water being reflected from the surface of the water, and consists of color from both dissolved and suspended components. Apparent color may also be changed by variations in sky color or the reflection of nearby vegetation.

  3. Thermochromism - Wikipedia

    en.wikipedia.org/wiki/Thermochromism

    The color change usually happens in a 3 °C (5.4 °F) interval. Leuco dyes are used in applications where temperature response accuracy is not critical: e.g. novelties, bath toys, flying discs, and approximate temperature indicators for microwave-heated foods. Microencapsulation allows their use in wide range of materials and products.

  4. Ocean color - Wikipedia

    en.wikipedia.org/wiki/Ocean_color

    Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean , while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1 ]

  5. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    Water at the top of the troposphere, particularly in liquid and solid states, cools as it emits net photons to space. Neighboring gas molecules other than water (e.g. nitrogen) are cooled by passing their heat kinetically to the water. This is why temperatures at the top of the troposphere (known as the tropopause) are about -50 degrees Celsius.

  6. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2] Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields.

  7. Iridescence - Wikipedia

    en.wikipedia.org/wiki/Iridescence

    The colour indicates the temperature it was heated to, making it one of the earliest practical uses of iridescence. Nanocellulose is sometimes iridescent, [ 28 ] as are thin films of petrol and some other hydrocarbons and alcohols when floating on water.

  9. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. [4] This can easily be observed in a water-filled bath or wash-basin whose lining is white. Large ice crystals, as in glaciers, also appear blue.
