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.
, Just love English Grammar. A word which is spelt and pronounced like another word but which has a different meaning is called Homonym. For example, hail(to describe somebody or something as being special or good) and hail( small balls of ice that fall as rain) and hail(to call to somebody to gain their attention).
