  2. Ice - Wikipedia

    en.wikipedia.org/wiki/Ice

    The impact on global temperatures from losing West Antartica, mountain glaciers and the Greenland ice sheet is estimated at 0.05 °C (0.090 °F), 0.08 °C (0.14 °F) and 0.13 °C (0.23 °F), respectively, [154] while the lack of the East Antarctic ice sheet would increase the temperatures by 0.6 °C (1.1 °F). [156] [157]

  3. Phases of ice - Wikipedia

    en.wikipedia.org/wiki/Phases_of_ice

    To create ice XVII, the researchers first produced filled ice in a stable phase named C 0 from a mixture of hydrogen (H 2) and water (H 2 O), using temperatures from 100 to 270 K (−173 to −3 °C; −280 to 26 °F) and pressures from 360 to 700 MPa (52,000 to 102,000 psi; 3,600 to 6,900 atm), and C 2 are all stable solid phases of a mixture ...

  4. Frigorific mixture - Wikipedia

    en.wikipedia.org/wiki/Frigorific_mixture

    Liquid water and ice, for example, form a frigorific mixture at 0 °C or 32 °F. This mixture was once used to define 0 °C. That temperature is now defined as the triple point of Water with well-defined isotope ratios.

  5. Melting point - Wikipedia

    en.wikipedia.org/wiki/Melting_point

    The melting point of ice at 1 atmosphere of pressure is very close [3] to 0 °C (32 °F; 273 K); this is also known as the ice point. In the presence of nucleating substances, the freezing point of water is not always the same as the melting point.

  6. Enthalpy of fusion - Wikipedia

    en.wikipedia.org/wiki/Enthalpy_of_fusion

    To heat 1 kg of liquid water from 0 °C to 20 °C requires 83.6 kJ (see below). However, heating 0 °C ice to 20 °C requires additional energy to melt the ice. We can treat these two processes independently and using the specific heat capacity of water to be 4.18 J/(g⋅K); thus, to heat 1 kg of ice from 273.15 K to water at 293.15 K (0 °C to ...

  7. Triple point - Wikipedia

    en.wikipedia.org/wiki/Triple_point

    For example, the triple point at 251 K (−22 °C) and 210 MPa (2070 atm) corresponds to the conditions for the coexistence of ice Ih (ordinary ice), ice III and liquid water, all at equilibrium. There are also triple points for the coexistence of three solid phases, for example ice II , ice V and ice VI at 218 K (−55 °C) and 620 MPa (6120 atm).

  9. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    For mid-level altocumulus and altostratus, the range is 0 to -20 °C. Vertical or multi-level cumulus, cumulonimbus, and nimbostatus, create icing at a range of 0 to -25 °C. High-level cirrus, cirrocumulus, and cirrostratus generally cause no icing because they are made mostly of ice crystals colder than -25 °C. [36]
