  The transverse momentum ($p_{\rm T}$) spectra of inclusive charged particles
and its dependence on charged-particle multiplicity are studied in pp
collisions at $\sqrt{s}$ = 7 and 13 TeV using the Monte Carlo event generator
PYTHIA Monash. The results of the minimum bias pp collisions are compared with
the ALICE published results at the same energies. The variations of the
effective temperature (T$_{\rm {Eff}}$) and average transverse momentum
($\langle p_{\mathrm{T}} \rangle$) with charged-particle multiplicity are also
studied. The $p_{\rm T}$ spectra of the charged particles are observed to get
harder with increasing charged-particle multiplicity. Moreover, a sharp
increase in the T$_{\rm {Eff}}$ and $\langle p_{\mathrm{T}} \rangle$ with
increasing multiplicity followed by a gradual decrease with the further
increase in multiplicity could also be observed. Further, it could be observed
that the color reconnection (CR) mechanism has a considerable effect on
flattening the T$_{\rm {Eff}}$ and $\langle p_{\mathrm{T}} \rangle$ with
increasing multiplicity, which indicates that phase-transition may not
necessarily be the only mechanism that could give rise to such an effect.
