Stoichiometry A perfectly insulated container of volume V is divided into two equal halves by a partition. One side is under vacuum, while the other side has one mole of an ideal gas (with constant heat capacity) at 298 K. If the partition is broken, the final temperature of the gas in the container Will be greater than 298 K Will be 298 K Can not be determined Will be less than 298 K Will be greater than 298 K Will be 298 K Can not be determined Will be less than 298 K ANSWER DOWNLOAD EXAMIANS APP
