Peer reviewedGislason, Eric A.; Craig, Norman C. – Journal of Chemical Education, 1987
Argues that previous definitions of work and heat are inappropriate. Presents new definitions that are formulated using experimental quantities, claiming that they apply equally well to reversible and irreversible processes. Indicates some of the problems with earlier definitions and applies the new definitions to the First Law of thermodynamics.…

Peer reviewedMeyer, Edwin F. – Journal of Chemical Education, 1987
Discusses some of the misconceptions commonly held suggesting that mixing ideal gases causes an increase in entropy. Argues that the combining processes and resulting total pressure have absolutely nothing to do with the mixing itself. (TW)

Peer reviewedGlasser, L. – Journal of Chemical Education, 1989
The evolution of ideas about the concept of chaos is surveyed. Discussed are chaos in deterministic, dynamic systems; order in dissipative systems; and thermodynamics and irreversibility. Included are logistic and bifurcation maps to illustrate points made in the discussion. (CW)
