Bluetooth operates at frequencies between 2402 and 2480 MHz, or 2400 and 2483.5 MHz including guard bands 2 MHz wide at the bottom end and 3.5 MHz wide at the top. This is in the globally unlicensed (but not unregulated) Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band.
The conversion between the two is 1000 kg/m3 to 1 g/cm3. Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm3. Water has the maximum density of 1 g/cm3 only when it is pure water.
The density of seawater at the surface of the ocean varies from 1,020 to 1,029 kilograms per cubic meter. 1020â1029 kg/m3 The density of an object is the ratio of its mass to its volume. Density can also be expressed as specific gravity, which is the ratio of the density of a material to the density of water. Where the density of water in SI units is 1000 kilogram per cubic meter. The density of seawater varies with temperature and salinity of the water. As temperature increases, density decreases. As salinity of the water increasaes, density also increases. Although the density of seawater varies at different points in the ocean, a good estimate of its density at the ocean's surface is 1025 kilogram per cubic meter. Its specific gravity is therefore 1.025.
