Melting point of the sample
&
Density of the sample
A disturbed sample is one in which the structure of the soil has been changed sufficiently that tests of structural properties of the soil will not be representative of in-situ conditions, and only properties of the soil grains (e.g., grain size distribution, Atterberg limits, and possibly the water content) can be accurately determined. An undisturbed sample is one where the condition of the soil in the sample is close enough to the conditions of the soil in-situ to allow tests of structural properties of the soil to be used to approximate the properties of the soil in-situ.
if you have a water sample that contains either nitrate chloride.
It is true.
Solubility and density
I have just looked at several online articles about Darmstadtium and it's melting point is not listed.

Take a simple random sample.
you will have to determine the properties of your sample, and compare these with a table of properties of metals. Density is a good easy one to start with. But you could consider colour, softness and so on.
The determination is by chemical analysis.
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.

If you had a piece of metal, you could use these properties to determine which element it is. Iron has different physical and chemical properties than the other two elements. The density of iron is much less than cobalt or nickel, and it reacts with oxygen in the air.
No. There are other ways of analyzing a sample to determine whether or not it is diamond, which does not dissolve in hydrochloric acid.
Inductive Reasoning
if the melting point range is between 0.5 to 1 degree celcius
A spectrophotometer can be used to know if a sample is DNA or RNA. DNA has an absorbance maximaat 260nm, whereas RNA has an absorbance maxima at 280nm. By looking at which one of these two wavelengths the sample is more excited, one can determine if the sample is DNA or RNA.
