  High-multiplicity proton-proton (pp) collisions at the Large Hadron Collider
(LHC) energies have created a new domain of research to look for a possible
formation of quark-gluon plasma in these events. In this paper, we estimate
various thermal properties of the matter formed in pp collisions at the LHC
energies, such as mean free path, isobaric expansivity, thermal pressure, and
heat capacity using a thermodynamically consistent Tsallis distribution
function. Particle species-dependent mean free path and isobaric expansivity
are studied as functions of final state charged particle multiplicity for pp
collisions at the center-of-mass energy $\sqrt{s}$ = 7 TeV. The effects of
degree of non-extensivity, baryochemical potential, and temperature on these
thermal properties are studied. The findings are compared with the theoretical
expectations.
