Delta (Chemistry)

In chemistry, "delta" (often written as Δ) represents a change or difference in a specific property, such as temperature, pressure, or energy, during a process. For example, ΔH denotes a change in enthalpy (heat content), while ΔG indicates a change in free energy. It’s a way to quantify how much something has increased or decreased as a reaction or process occurs. Essentially, delta is a symbol used to measure the amount of change between the initial and final states of a system.
