The quality or state of becoming warm or hot; the process of growing warm.
From Latin 'calescere' (to grow warm), derived from 'calere' (to be hot). The suffix '-ence' creates an abstract noun indicating a state or condition.
While 'heat' is straightforward, 'calescence' specifically captures the *process* of warming up—it's the word for that gradual transition from cold to hot!
