1. An ideal gas assumes molecules are point particles and do not interact with each other. In reality, molecules occupy space! To correct for this, the ideal gas equation of state is adjusted to take the volume occupied by the molecules into account for a real gas: PV = nRT or P = nRTV is modified to P = nRT/(V-nb) (IDEAL GAS) (REAL GAS Where "b" is related to the...
