No.

*not* the symbol for entropy. Sometimes,

#q = msDeltaT# where:

#q# isheat flowin#"J"# . In ispositive, and out isnegative.#m# ismassin#"g"# .#DeltaT# ischange in temperaturein#"K"# or#""^@ "C"# .

**Entropy**, however, is featured as

#\mathbf(DeltaG = DeltaH - TDeltaS)# where:

#DeltaG# is theGibbs' Free Energyin#"kJ/mol"# .#DeltaH# is theenthalpyin#"kJ/mol"# .#T# is thetemperaturein#"K"# .#DeltaS# is theentropyin#"J/K"cdot"mol"# .

The capitalization matters.
