Water has a density of 1000 kg/m3 by standard definition at its temperature of maximum density 3.98 Â°C and at 0% salinity. Scientists and engineers use water as a baseline for comparing the relative density of various materials. Water with a density of 1000 kg/m3 at 3.98 Â°C has a mass of 1000kg and a volume of 1 m3.
Spelt is a word. It is the past participle of spell. It is also a type of wheat, and therefore also a noun. It depends upon whether you are using British English (and Spelt is correct) or you are using American English.
Spelt (Triticum aestivum var. spelta) is a sub-species of common wheat. It has been grown in Europe for about 300 years. Spelt was introduced to the United States in the 1890s. Most of the nation's spelt acreage is in Ohio.
