WebMay 15, 2024 · Volatile matter is an unstable material. Volatile matter tends to not remain in one state and will rapidly transition to another state, or vaporize, when the right conditions are met. Volatile matter has its volatility determined not by temperature but more so by the vapor pressure required to initiate a phase change. Advertisement.
