What does Volatile mean:
A volatile liquid evaporates faster because of it's low boiling point.
Volatile liquids may be ethers, alcohols, ketones etc.
volatile int means the code and fom outside from code can changes the value but in const volatile int, code cannot changes the value but fron ouside can change the value
It is oil that will evaporate at normal temperature and pressure.
RAM is volatile storage, short-term storage or working memory. As opposed to a hard-drive which is non-volatile, long term storage or a mass-storage medium.
'int' is the type, 'volatile' warns the compiler, that the value might be changed asynchronousy, so it mustn't be optimized (e.g. cached in register.)
Combustible.
volatile
Volatile means to evaporate rapidly. Non volatile would then be not aromatic. If you can smell an oil then it is most likely evaporating. Can you smell the coriander? Then you are smelling the oils. This doesn't mean that there are not non volatile oil (glyrerides) in the spice.
Alcohol vapourises faster than liquid because it is a volatile fluid
