Yes, of course the most obvious fact about water is that it is wet, at least in the liquid state. For example, this means that buying 1.5l bottle of mineral water, we need to bring home about 1.5 kg, etc. For pure water, the density is 1 gm/cm3 or 1000 kg/m3. The higher the altitude, the lower the air pressure, the lower the boiling point of water, and thus, the longer time to hard-boil an egg. This approximation is very practical (and generally sufficiently accurate for everyday activities), because then 1l of water weighs approximately 1 kg. density of water, pure is equal to 1 000 kg/m³ at 25☌ (77☏ or 298. In everyday life, it is often assumed to approximate the water density to 1000 k g / m 3 kg/m^3 k g / m 3. Water, pure weighs 1 gram per cubic centimeter or 1 000 kilogram per cubic meter, i.e.in the so-called normal conditions), the water density is equal to 1000 k g / m 3 kg/m^3 k g / m 3. The density of ocean water:-At the sea surface, the density of ocean water is approximately 1027 kg/m 3. The density of freshwater:-Freshwater has a density of 1g/cm 3 or 1000kg/m 3. Pure water has a density of 1g/cm 3 or 1000kg/m 3. Both below and above this temperature, the density of water is lower. The density of pure water:-The density is defined as the mass per unit volume ratio. The density of water reaches its maximum around 4☌.For some substances this effect is significant, in case of others it may be small.
