![]() ![]() I was a kid back then and weighed only 70 pounds. Then they asked me to return home, get a gallon of water and bring it to them to quench their thirst. It was a hot summer day, and they went up this nearby hill to bury their collection of bottle caps. There was a time in my life when I could use this concept of water density to get back at my older brother and his friends for always picking on me. One example that can be made for this is molten silica. ![]() This phenomenon is usually referred to as ‘negative thermal expansion’ and applies to those bonded with intermolecular forces and other chemical composition factors. There are cases where it is usually the other way around, where further cooling of a substance decreases its density.But the limit ends at 4☌, where pure water is at its most dense. Of course, this is true for other substances as well. When water is cooled at room temperature, it becomes denser over time.Temperature can also change water density, but the correlation is still unclear and inconsistent.The density of water is approximately 1 gram per cubic centimeter (1 g/cm3) or 1 gram per milliliter (1g/mL).The following are the common factors that affect the density of water. It is simply just its weight for every specific volume.įor example, water’s density under normal conditions is 0.9998395 g/ml at 4.0° Celsius (39.2° Fahrenheit), to be specific but is rounded off to 1 gram per mL or cubic centimeter (1g/mL or cc) for uniformity. In other words, if an object occupies space and has mass, its density can also be measured. Mass and weight are often misused because of the confusion about their respective definitions, but since we are only referring to one gravity of Earth, mass and weight are pretty much the same.ĭensity is a constant factor in all matter that is composed of molecules. That is the technical definition of the term. The sentence “Density is the mass per unit volume of a substance” is always mentioned in class. ![]()
