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 distilled water is same as that of pure water as it does not contain any impurities or salt content in it. The density of distilled water is 1 g/cm3, 1 kg per litre, 1 tone per m3 or one gram per ml. The Density of tap water is 1 gram/cm3 and 1 gram per milliliter.It should be noted that mostly all the densities are the same. They differ in only points but the approximate values are used in calculations. The density of Ice is 0.9167 gm/cm 3 and the density of water is 0.9998 gm/cm 3.he density of distilled water is 1 g/cm3, 1 kg per litre, 1 tone per m3 or one gram per ml. The Density of tap water is 1 gram/cm3 and 1 gram per milliliter. It should be noted that mostly all the densities are the same.
