  2. Cold shock response - Wikipedia

    en.wikipedia.org/wiki/Cold_shock_response

    Water has a thermal conductivity 25 times and a volume-specific heat capacity over 3000 times that of air; subsequently, surface cooling is precipitous. The primary components of the cold shock reflex include gasping, tachypnea, reduced breath-holding time, and peripheral vasoconstriction, the latter effect highlighting the presumed physiologic ...

  3. Freezing air temperature - Wikipedia

    en.wikipedia.org/wiki/Freezing_air_temperature

    Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.

  4. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [ 1 ]

  6. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    In the above equation, T F is the normal freezing point of the pure solvent (273 K for water, for example); a liq is the activity of the solvent in the solution (water activity for aqueous solution); ΔH fus T F is the enthalpy change of fusion of the pure solvent at T F, which is 333.6 J/g for water at 273 K; ΔC fus p is the difference ...

    What to do when water pipes freeze. Here are tips from The Red Cross. If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Likely places for frozen pipes include against ...

  8. Capillary action - Wikipedia

    en.wikipedia.org/wiki/Capillary_action

    Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.

  9. Cold trap - Wikipedia

    en.wikipedia.org/wiki/Cold_trap

    Cold traps (C in the figure) usually consist of two parts: The bottom is a large, thick round tube with ground-glass joints (B in the figure), and the second is a cap (A in the figure), also with ground-glass connections. The length of the tube is usually selected so that, when assembled, the total reached is about half the length of the tube.
