The first estimation of the isothermal compressibility ( k T ) of matter is presented for a wide range of collision energies from √s NN = 7.7 GeV to 2.76 TeV. k T is estimated with the help of event-byevent charged particle multiplicity fluctuations from experiment. Dynamical fluctuations are extracted by removing the statistical fluctuations obtained from the participant model. k T is also estimated from event generators AMPT, UrQMD, EPOS and a hadron resonance gas model. The values of isothermal compressibility are estimated for the Large Hadron Collider (LHC) energies with the help of the event generators.
