Abstract * : With an adaptation of second order Godunov-type PLUTO code, we present a model of the kinematics and evolution of the isolated impulsive solar jets in the solar atmosphere. These chromospheric jets are originated due to the propagation of pressure pulse in 1-dimension from the chromosphere upward. These jets may act as input for the energy and mass transfer in to the upper solar atmosphere (i.e lower solar corona). The height-time profiles of the jets , which are originated due to different pressure pulses, exhibit the asymmetric near parabolic profiles. The upward motion of these jets are governed by the influence of pressure perturbation, while their downfall is governed by free fall of the plasma. The maximum height, lifetime profiles w.r.t. pressure pulse strength exhibit linear behavior. Therefore, we conjecture that if we increase the heating and associated pressure perturbations, there are longer chromospheric jets that do possess higher life-time
