The melting point of a substance should be considered a property of its crystalline form only. At the melting point the liquid and solid forms of a substance exist in equilibrium. All substances of crystalline nature have their characteristic melting points. For very pure substances the temperature range over which the process of fusion occurs is very small. The melting point of a pure crystalline solid is a function of pressure; it increases with increasing pressure for most substances. However, in the case of ice (and a few other substances) the melting point decreases with increasing pressure ... Under a pressure of one standard atmosphere, the melting point of pure ice is the same as the ice point, that is, 0°C. 7, record 3, English, - melting%20point

Most musical instrument wood is dried to a 7% to 10% moisture content. However, the wood will forever allow moisture to pass into and out of its structure. Each variety of wood has what is called its equilibrium moisture content(EMC). This is the moisture level at which the wood is at rest naturally at a given atmospheric temperature and humidity. It is not constant. When the air is wetter, there will be moisture absorbed by the wood to a new wetter level, which is not the same amount as the moisture level in the air. 4, record 4, English, - stringed%20instrument%20wood

The "critical moisture level" for a particular type of seed is the percentage moisture of the seed when it is in equilibrium with an atmospheric RH [relative humidity] of about 70% at 25 degrees C.

The trace element iron has been recently shown to play a critical role in nutrient utilization, phytoplankton growth and therefore the uptake of carbon dioxide from the surface waters of the global ocean. Carbon fixation in the surface waters, via phytoplankton growth, shifts the ocean/atmosphere exchange equilibrium for carbon dioxide. As a result, levels of atmospheric carbon dioxide(a greenhouse gas) and iron flux to the oceans have been linked to climate change(glacial to interglacial transitions). These recent findings have led some to suggest that large scale iron fertilization of the world's oceans may therefore be a feasible strategy for controlling climate. 2, record 6, English, - iron%20fertilization

The calculations for the ISS [International Space Station] quasi-steady acceleration environment can be compared to a set of formal design requirements which state that 50 percent of the ISPR [International Standard Payload Rack] locations within the U.S. Lab, Columbus and the JEM must have quasi-steady accelerations below 1 ug for periods of 30 continuous days a total of 6 times per year. The operation of the Station in Microgravity Mode is designed to produce these 30 day intervals. The quasi-steady acceleration vector has an additional directional stability requirement stating that the component perpendicular to the vector’s orbital average must be less than or equal to 0.2 [mu] g. To meet this requirement the Station’s attitude must be controlled during orbit so that it maintains a constant position relative to the LVLH [Local Vertical/Local Horizontal] axes. 2, record 7, English, - quasi%2Dsteady%20acceleration%20environment

The quasi-steady state acceleration level is determined primarily by the combined effects of atmospheric drag(due to the finite residual Earth's atmosphere at the orbital altitude of the ISS), and gravity gradient stabilisation of the ISS. Gravity gradient stabilisation uses the principle that a body in orbit around the Earth will tend to rotate about it's centre of mass, as each part of the body will tend to follow it's own orbit. It will normally oscillate about a mean orientation, but will eventually remain in a stable orientation with respect to the Earth. The normal orientation for the ISS is the Torque Equilibrium Attitude discussed earlier. The resultant combination of atmospheric drag, gravity gradient and other secondary effects produce a set of gravity contours(i. e., locations of equal gravity level) which define the quasi-steady state microgravity environment of the ISS. 3, record 7, English, - quasi%2Dsteady%20acceleration%20environment

What determines the chemistry of rain and snow? The water comes from evaporation and transpiration(water vapor lost by plants) and is essentially distilled, or pure. Once the vapor reaches the atmosphere, however, it condenses on solid particles and soon reaches equilibrium with atmospheric gases. One of the gases is carbon dioxide(CO2), and as carbon dioxide dissolves in the water carbonic acid(H2CO3) forms. Carbonic acid, being a weak acid, dissociates only slightly in distilled water, yielding hydrogen ions and bicarbonate ions(HCO3-). At normal concentrations and pressures of carbon dioxide in the atmosphere the pH of rain and snow would be 5. 6. 1, record 12, English, - chemistry%20of%20snow
