The temperature of maximum density is 3.98 C (or 39.16 F)when the density of "air free" water is 1.00000 g/cm3. It is less dense at both colder and warmer temperatures. As to why, this has to do with the molecular structure of wat...

Density - Wikipedia, the free encyclopedia
The density of a material is defined as its mass per unit volume. The symbol of density is ρ (the Greek letter rho). Mathematically: \rho = \frac{m}{V} \, where: \rho (rho) is the density...

Water (properties) - Wikipedia, the free encyclopedia
Water ( , HOH) is the most abundant molecule on Earth's surface, constituting about 75% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibr...

As liquid water cools, more and more hydrogen bonds are formed and maintained. This increased attraction with decreasing temperature continues until 40°F (4°C) when water is at its densest. ... Water is least dense at 32°F (0°C). Within a 8°F (4°C) temperature range water can be found at its densest and lightest.

As a liquid, the behavior of water differs from all other fluids. The latter become consistently and steadily denser with cooling, water reaches its densest state at a temperature of +4o C (+39.2o F), below which it grows less dense.

Therefore the water remains liquid at 242 Degrees Fahrenheit. Liquid propane reacts in much the same way to temperature and pressure as water, its just that the boiling point of propane is much lower on the thermometer.

Temperature is also important because of its influence on water chemistry. The rate of chemical reactions generally increases at higher temperature, which in turn affects biological activity. An important example of the effects of temperature on water chemistry is its impact on oxygen.
