# Reading equations: states and conditions

> Reading physical-state symbols (s), (l), (g), (aq), (v), the heating sign (Δ) written over the arrow, and conditions or catalysts written over the arrow (temperature, pressure, catalyst).

> [ar-EG] إنك تقرا الـ state symbols اللي بتيجي بعد المادة في المعادلة: (s)، (l)، (g)، (aq)، (v)، وعلامة التسخين (Δ)، والـ conditions أو الـ catalysts اللي بتتكتب فوق السهم (temperature، pressure، catalyst).
