Abstract: The Paper begins with elementary concepts of Entropy from basic thermodynamic considerations. Entropies of Magma in the Chamber, the intruding magma and the entropy after intrusion are considered. The physical state of affairs after intrusion leading to eruption is dealt with in a systematic manner. In the Conclusion, without going into details, the author has just mentioned the name of Edward Lorenz of Chaos theory

Keywords: Chaos, Convection of Magma, Entropy, Eruption, Isochoric process, Magma, Magma Chamber, Magma Intrusion, Principle of Increase of Entropy, Specific heat, Volume of Magma Chamber
