In 2007, Parker Brothers began releasing its standard version (also called the Speed Die Edition) of Monopoly with the same die [131] (originally in blue, later in red). Its faces are: 1, 2, 3, two "Mr. Monopoly" sides, and a bus. The numbers behave as normal, adding to the other two dice, unless a "triple" is rolled, in which case the player ...
The water is full of salts, selenium, and fertilizers (mainly nitrates). [31] As it drains through the soil, the water leaches out ancient salt deposits that also raise the salinity. Evaporation in the desert heat further concentrates the salt. The transformation of the lake made it increasingly inhospitable to wildlife.
The heater is a plastic bag filled with magnesium and iron powders and table salt. When a meal pouch is placed in the bag and water is added, an exothermic reaction occurs which rapidly boils the water to heat the food. The U.S. Army began research into a chemical method to heating meals in 1973. The FRH was first issued in May 1990, and an FRH ...
Most fresh water – about 69% – is present as ice in ice caps and glaciers. [20] The average salinity of Earth's oceans is about 35 grams (1.2 oz) of salt per kilogram of seawater (3.5% salt). [21] Most of the salt in the ocean comes from the weathering and erosion of rocks on land. [22]
Salt poisoning is an intoxication resulting from the excessive intake of sodium (usually as sodium chloride) either in solid form or in solution (saline water, including brine, brackish water, or seawater). Salt poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer. The lethal dose of ...
In food science, water activity (a w) of a food is the ratio of its vapor pressure to the vapor pressure of water at the same temperature, both taken at equilibrium. [1] Pure water has a water activity of one. Put another way, a w is the equilibrium relative humidity (ERH) expressed as a fraction instead of as a percentage.
The water cycle is also essential for the maintenance of most life and ecosystems on the planet. Human actions are greatly affecting the water cycle. Activities such as deforestation, urbanization, and the extraction of groundwater are altering natural landscapes (land use changes) all have an effect on the water cycle.
Water will diffuse into the fish, so it excretes a very hypotonic (dilute) urine to expel all the excess water. A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water (to the more negative surroundings) and gain salt. It actively excretes salt out from the gills.
