3400 to 37,500 kg-force/cm 3 [2] ... The density of ice increases slightly with decreasing temperature and has a value of 0.9340 g/cm 3 at −180 °C (93 K). [7]
The specific heat capacity of ice at −10 °C is 2030 J/(kg·K) [30] ... [31] Density of water and ice. Density of ice and water as a function of temperature.
[54] [55] The density of ice is 917 kg/m 3 (57.25 lb/cu ft), an expansion of 9%. [56] [57] This expansion can exert enormous pressure, bursting pipes and cracking rocks. [58] In a lake or ocean, water at 4 °C (39 °F) sinks to the bottom, and ice forms on the surface, floating on the liquid water.
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
Typically about one-tenth of the volume of an iceberg is above water, which follows from Archimedes's Principle of buoyancy; the density of pure ice is about 920 kg/m 3 (57 lb/cu ft), and that of seawater about 1,025 kg/m 3 (64 lb/cu ft). The contour of the underwater portion can be difficult to judge by looking at the portion above the surface.
Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
The most common form on Earth, low-density ice, ... it was shown that the difference in volume between ice II and ice III was in the range of 0.0001 m 3 /kg ...
As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...
