Slate is a rock of mixed mineral composition and does therefore does not possess a uniform Mohs hardness. Because of varying porosity along with other factors, the elastic modulus, or measurement of stiffness, of various slate specimens will vary.
the varying ability to conduct electric current
Cocoyam contains varying amounts of calcium oxalate, potassium, zinc and magnesium. The proportions of these substances depend on the exact variety of the cocoyam.
Not if they are solid substances (ie one is not hollow in the middle). That was how Archamedies worked out how to prove the gold crown was pure gold. The density of every substance (mass per unit volume) is unique. * * * * * Not so sure about the density of EVERY substance being different. Every PURE substance: probably yeas. But every substance? For example, the density of steel can be varied from 7.75 gcm-3 to 8.05 gcm-3, by varying the proportion of the other materials in the alloy. Presumably there are some other substances with a density in that range.
There are many varying physical properties used to identify a pure substance. Some of the most prevalent physical properties are color, odor, density, melting and freezing points and solubility.
A pure substance has a fixed and uniform composition.
No. A compound will always have the same composition.

It's when the anwser varies from things to things
A pure substance is one which contains only that substance and nothing else. An impure substance contains other substances in varying amounts.
The composition of the soil according to varying proportions of different sized particles.
the varying ability to conduct electric current
Non-uniform motion refers to the type of motion where the speed or direction of an object is changing over time. In non-uniform motion, the object is not moving at a constant speed or in a straight line. Instead, its velocity is varying, and it may be accelerating or decelerating.
A combination of varying pressure and/or temperature.
Propulsion by means of uniform cross sectional ducts rather than a varying section (nozzle) is said to be nozzleless propulsion
In air wedge there is uniform separation between the two slabes but in Newtons ring the thickness is varying
Basically duralamin is a substance found on the lining of sheep intestines. It is a bround substance of varying viscocities. Duralamin can be found in fields in small piles like bunches of berries.
