Knowing the conductivity of an unknown substance helps identify its ionic or molecular nature, which is crucial in various fields such as chemistry, materials science, and environmental monitoring. Conductivity can indicate the presence of dissolved ions, revealing information about the substance's purity and potential applications. Additionally, it can aid in assessing the substance's behavior in different environments, such as its suitability for electrical applications or its impact on biological systems. Understanding conductivity is essential for quality control and ensuring safety in industrial and laboratory settings.
yes
You multiply the volume by the density of the substance.
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
If you mean what substances are present in paper, then it is principally cellulose. If you are asking about substance A in a question paper, it's a way of referring to an unknown substance so it can ask you questions based on the information given about it. For instance, if it says 'substance A turns damp red litmus blue' then you know that substance A is an acid.
There are no known atoms that are completely unknown to science. However, there may be undiscovered elements beyond those listed on the periodic table. These elements would have their own unique properties and characteristics that have yet to be studied.
To answer that you would need to know the size (volume) of the box.
if they are unknown how would be know about them?
It they are unknown how would we know if they are unknown
an unknown substance is when you smell something and it can lead to any formula like exasopei and or hologrophuclas i know it sounds silly but its true
The electrical conductivity is measured.
If it's still unknown, how would anybody know it?
The definition of "unknown" is that nobody knows - so how would we know if there were?
There is no answer to your question. If the facts were unknown, then nobody would know them, right?
The electrical conductivity is not know, Thermal conductivity is 0.00565 W/(m·K)
Unknown substances are materials whose composition or properties are not readily identifiable or known. These substances may require analysis or testing to determine their characteristics, which can help determine their potential uses or hazards. It is important to handle unknown substances with caution until their nature is determined.
yes
If the interesting facts are unknown, I would not know them.
