Does the density change with temperatures
WebWater density is typically rounded to 1 g/cm 3 or 1000 kg/m 3, unless you are doing very exact calculations or conducting an experiment in extreme temperatures. Water's density changes depending on the … WebWater density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point). Why does ice float in water? Each water molecule is made up of two hydrogen (H) atoms and one oxygen (O) atom. The bonds between water molecules are called ...
