This opaque mineral shows a dull, or dully-metallic luster and is typically black or brown-black in color, typically shows no strong cleavage, has a hardness of 5.5 - 6.5 and produces a black streak, has a specific gravity of 5.2, may react weakly with HCl, is strongly magnetic and will attract iron filings. What is this mineral

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
