The neutral value of the pH depends on the temperature and is lower than 7 if the temperature increases above 25 °C. The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases .
The car came with normal Chevrolet warranty as well as an additional one year 12,000-mile warranty from Callaway Cars. The conversion cost an extra US$26,995 over the price of a base model Corvette. The conversion consisted of taking the engine out of the car and performing a thorough set of modifications along with installing two turbochargers.
At standard temperature and pressure, it forms a monatomic gas with a density of 9.73 kg/m 3, about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3. [16] It is one of the densest gases at room temperature (a few are denser, e.g. CF 3 (CF 2) 2 CF 3 and WF 6) and is the densest of the noble gases.
At a pressure of 1 atm (0.101325 MPa), the gas deposits directly to a solid at temperatures below 194.6855(30) K [2] (−78.4645(30) °C) and the solid sublimes directly to a gas above this temperature. In its solid state, carbon dioxide is commonly called dry ice. Pressure–temperature phase diagram of carbon dioxide. Note that it is a log ...
The highest temperature recorded in Perth was 46.2 °C (115.2 °F) on 23 February 1991, although Perth Airport recorded 46.7 °C (116.1 °F) on the same day. [ 85 ] [ 86 ] On most summer afternoons a sea breeze , known locally as the Fremantle Doctor , blows from the south-west, providing relief from the hot north-easterly winds.
Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S 8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth.
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [1] The concept of an expanding universe was scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations.
Anhydrous dextrose has the chemical formula C 6 H 12 O 6, without any water molecule attached which is the same as glucose. [39] Anhydrous dextrose on open air tends to absorb moisture and transform to the monohydrate, and it is more expensive to produce. [ 41 ]
