Noun

1. A chemical or compound that changes into a gas easily.
2. (programming) A variable that is volatile, i.e. has its associated memory immediately updated with any change in value.
   • 2011, Victor Pankratius, Ali-Reza Adl-Tabatabai, Walter Tichy, Fundamentals of Multicore Software Development, page 74:

     Operations on C++ volatiles do put the compiler on notice that the object may be modified asynchronously, and hence are generally safer to use than ordinary variable accesses.
