How do you represent a Delta?

Delta Symbol: Change

Uppercase delta (Δ) at most times means “change” or “the change” in maths. Consider an example, in which a variable x stands for the movement of an object. So, “Δx” means “the change in movement.” Scientists make use of this mathematical meaning of delta in various branches of science.

What does ∆ mean in Greek?

The upper-case delta (Δ) is used to represent "difference" or "change" in mathematics. As well as the phrase "River delta" takes its name from the upper-case delta. The lowercase Delta (δ) is used to denote a partial charge in molecular chemistry. This Greek symbol has a meaning in law too.

Why is delta the symbol for change?

It's used because of the word difference, whose latin etymology happens to start with a "d" also. Differ comes from the latin word differre, derived from the word ferre which can often be translated by "carry". Pretty much every word which contains the word "differ" is derived from this.

What does ΔH f mean?

Standard Enthalpy of Formation, ΔH∘f

The standard enthalpy of formation (ΔH∘f) is defined as the enthalpy change for creating one mole of a compound from elements in their standard states. The standard states are the form you would find an element in at 1 bar pressure and 25 °C.
