Tending toward decomposition or another state, or as produced or transported, will vigorously polymerize, decompose, condense, or become self-reactive under condition of shocks, pressure, or temperature.
when a chemical is unstable it means that the chemical can change into other chemicals easily, or react with other substances. Ozone is unstable and it can react with our lungs to damage the tissues. (Back to Ozone Action! Days)
A turbulent state in the atmosphere, often caused by cold air moving over warm air. Unstable conditions are also induced by cold air moving over warm water and by strong heating of the ground by the sun. Convection develops when the atmosphere is unstable. Back to the top
Mineral with a crystal structure that is unable to exist at the current temperature. When certain minerals become unstable, they transform into their paramorphs. Also refers to radioactive minerals which cannot withstand their composition and begin to decay.
