One kmol of argon at 300 k is initially confined to one side of a rigid, insulated container divided into equal volumes of 0.2 m3 by a partition.
the other side is initially evacuated. the partition is removed and the argon expands to fill the entire container.
using the van der waals equation of state, determine the final temperature of the argon, in k.
