An ideal gas is confined to one side of a rigid, insulated container divided into equal volumes by a partition. The other side is initially evacuated. The following data are known for initial state of the gas: p1 = 300 kPa, T1 = 380K and V1 = 0.025 m3. The partition is now removed, and the gas expands to fill the entire container. Determine the final equilibrium pressure, in kPa.
