Halpern, Arthur M.; Noll, Robert J. – Journal of Chemical Education, 2019
A spreadsheet-based exercise for students is described in which they are challenged to explain and reproduce the disparate temperature dependencies of the heat capacities of gaseous F[subscript 2] and N[subscript 2]. For F[subscript 2], C[subscript p,m] increases from 300 K, reaches a maximum at 2200 K, and then decreases to 74% of the maximum…

Kirchner, Nina; van Dongen, Eef; Gowan, Evan J.; Pattyn, Frank; Noormets, Riko; Jakobsson, Martin; Ingólfsson, Ólafur – Journal of Geoscience Education, 2018
GRANTISM (GReenland and ANTarctic Ice Sheet Model) is an educational Excel™ model introduced by Pattyn (2006). Here, GRANTISM is amended to simulate the Svalbard-Barents-Sea Ice Sheet during the Last Glacial Maximum, an analogue for the contemporary West Antarctic Ice Sheet. A new name, "GRANTSISM," is suggested; the added S represents…
