The density of water is a fundamental physical property that is often used in various scientific calculations. At standard temperature and pressure (STP), which is typically defined as 0°C (32°F) and 1 atmosphere of pressure, the density of water is approximately 1 g/ml.
This means that one milliliter of water weighs one gram. The density of water can change slightly with temperature and pressure, but for most practical purposes, especially at room temperature, the density is considered to be 1 g/ml.
Understanding the density of water is crucial in fields such as chemistry, physics, and engineering, where precise measurements are necessary. It also helps in everyday applications, such as cooking and measuring liquids.
