Why does water have a maximum density at +4 deg C ? Is water unique in having this peak in density not at an extremity of the temperature range of a single (i.e. liquid in the case of water) state? Is this property of water the single most important reason for life to have evolved on this planet?
Density is calculated by dividing the mass by the volume. Plug in our measured mass at 100 grams and divide that by our measured volume of 100 ml. Water's density is 1 g/ml. Objects with a density greater than 1g/ml will sink when placed in water. Objects with a density less than one will float when placed in water. If a block has a density of 0.1g/cm3 it will float because it's density is less than 1.
