What are the intensive, physical, and chemical properties of matter?

Your question could be broken down into two categories: physical versus chemical properties, and intensive versus extensive properties.


Physical properties of matter have to do with features that can be measured and with the material by itself.  Some examples include melting and boiling points, color, density, state of matter at SATP (gas, liquid, solid), odor, conductivity, hardness, etc.  Chemical properties have to do with how the substance interacts with other substances.  Examples include combustibility or reactivity with acids/bases. Notice that the chemical examples require another substance to be present to interact (or not) with the material you are studying.


Extensive and intensive properties are further sub-categories of physical properties.  Intensive properties do not depend on the amount of matter.  Things like hardness, color, odor, and density fit in here.  Extensive properties are dependent on the amount of the material.  This includes things like mass and volume.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
