Abstract
In this work the results of molecular dynamics simulations of silica at different constant pressures are reported. These are compared with the constant-volume simulation results of the same system. The thermodynamic properties of these simulations were found to be dependent on the condition imposed on the system. The lowering of constant pressure on the system decreases its fictive glass-transition temperature. The structural properties of the simulated glasses were found to be less sensitive to these external conditions.
