    We explore the spectra of transverse momenta of hadrons with strange quark content (K 0 S , ϕ, Λ + Λ, Ξ + Ξ+ , and Ω -+ Ω+ ) produced in proton-proton collisions at √ s N N =7 TeV. We applied Tsallis statistics in a blast wave model (T BW ) to the ALICE Collaboration's experimental data, and extracted the freezeout parameters (Tsallis temperature, transverse flow velocity, and the paramater q which is the non-extensive parameter). The changing trend of these parameters is studied with changing multiplicity. The parameter q decreases while the parameter T and β T increases toward higher multiplicities. β T is noted to drop to zero in the system with the lowest multiplicities. Besides, the interrelationship between the parameter T with β T , and T with q is presented where the former correlation is positive and the later one is negative.
