A pure substance has a fixed and uniform composition.
No, always has one composition.
a pure substance made of more than one element is a compound.
The most important property of metalloids is that they are god and bad conducters of heat and electicity and have good and bad amount of metalic shine. the conducter one is more important though
In a 14K gold alloy, approximately 58.3% is pure gold, while the remaining percentage comprises other metals. The specific composition ensures durability and varying shades in jewelry design.
I guess the question is related to neon lamps rather than element neon. Neon lamps do use xenon gas it it. By varying the composition of gases used, the colour given out by the neon lamps can be changed.
A substance is any matter, any material which has mass and occupies space. As far as a specific substance, a material has a specific constitution.An element is a pure substance which cannot be broken down into (or synthesized by) other substances.For example, water is a substance, but water itself is the result of the union of two other elements, hydrogen and oxygen.An element cannot be made by joining other substances together (example, gold).
No. A compound will always have the same composition.
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.
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.
The property that makes semi-metals useful as "switches" is that their varying ability to conduct electricity.
