De thermodynamische relaties voor compressibele stoffen en de fasendiagrammen voor pure stoffen …
De thermodynamische relaties voor compressibele stoffen en de fasendiagrammen voor pure stoffen worden behandeld. Enkele voorbeelden van toestandsvergelijkingen worden behandeld (de viriaal vergelijking, vergelijkingen met twee constanten en vergelijkingen met meerdere constanten). De grootheden Helmholtz energie en Gibbs energie worden geintroduceerd. De Gibbs vergelijking is de basis om tot een beschrijving van evenwichten (van mengsels) te komen. De condities van evenwicht van pure componenten en van mengsels wordt afgeleidt. Uitgaande van de totale differentialen worden partiele afgeleide uit gedrukt in termen van thermodynamische grootheiden. Voor de berekening van processen, zo als compressie, expansie enz worden uitdrukkingen afgeleid voor delta h, delta s en delta u (waarbij delta voor de deviatie="departure" van ideaal gas gedrag staat). Het wordt getoond hoe deze uitdrukkingen (of dimensieloze diagrammen van deze grootheden) voor de berekening van processen gebruikt kunnen worden. Ook wordt de grootheid exergie gepresenteerd, een grootheid die gebaseerd is op de tweede hoofdwet van de thermodynamica, tezamen met enkele nuttige grootheden en hulpmiddelen voor het uitvoeren van exergie analyses (exergie verlies, exergie rendementen, waardediagram). In dit college wordt de definitie van exergie beperkt tot de thermo-mechanische exergie. Het principe van het stoomturbine kringproces wordt getoond en mogelijkheden voor de optimalisatie van dit kringproces worden besproken, zoals de keuze van stoomdruk en -temperatuur en de toepassing van stoomoververhitting en -herverhitting.

Developed by a team of scientists from two national laboratories, education researchers, gamers, and a professional game developer, Thirst for Power is a challenging, fast-paced, fun-to-play resource management card game in which players acting as governors of different regions of the country compete to be the first to meet their citizens' energy needs. Through game play, players come to understand how three manifestations of the extreme amplification of the human populationâexploding worldwide demand for energy, increasing exploitation of water resources, and alteration of the planet's climateâare tightly intertwined at the nexus of energy, water, and climate; one cannot be considered in isolation from the other two. Development was supported by the National Science Foundation.

Part 1
The SAGUARO Exploring GIS Investigations for Earth Science curriculum requries the use of ESRI's ArcView GIS software version 3.0 for Macintosh or 3.2 and higher for PC. Use ArcGIS and data files from the SAGUARO Project's (http://pro.arcgis.com/en/pro-app/help/projects/supported-data-types-and-items.htm) Exploring Tropical Cyclones investigations. After the students are introduced to the program they are asked to determine what criteria are required for the formation of tropical cyclones. Exploring Tropical Cyclones Unit 1 has a great deal of data for the students to use. The data is presented as layers on a world map. Different features can be turned on and off at will, and layers can be brought in from other units if desired.
Features they can work with are:
August SST February SST tropical cyclone tracks locations of tropical cyclone formation for Jun-Sep locations of tropical cyclone formation for Dec-Mar
Part 2
Students are divided into small groups (3-4 students works well) where they compare their findings (including what evidence they used) with the findings of the other group members. Each group is then asked to determine the threshold temperature for tropical cyclone formation as well as to calculate the area of the ocean that has SST equal to or above this threshold temperature (you can have them calculate this for each season, or as a total area including both February and August data).
Part 3
Class discussion of what they have found so far. Introduce them to model predictions of SST for different atmospheric CO2 levels. Propose a 2 degree C increase in tropical SST and ask what they think that will mean. What other factors might influence the formation of tropical cyclones?
Part 4
Assign an article or two (ideally a published peer reviewed article - to introduce them to this type of scientific writing - that is if you can find one that you consider appropriate for your students) that introduces them to other factors required for tropical cyclone formation and predictions of how climate change might affect them. For example an article that discusses the role of wind speed near the surface of the ocean, or vertical wind shear, or one that shows that the threshold temperature is actually predicted to increase by the same magnitude as the SST increase. Have them write a report that summaries the criteria for cyclogenesis as well as explaining how they would go about predicting where tropical cyclones will form as a result of an increased SST. They do not need to perform all of the tests they propose! They should state what sort of information they would like to obtain and why.

Students learn about tsunamis, discovering what causes them and what makes them so dangerous. They learn that engineers design detection and warning equipment, as well as structures that that can survive the strong wave forces. In a hands-on activity, students use a table-top-sized tsunami generator to observe the formation and devastation of a tsunami. They see how a tsunami moves across the ocean and what happens when it reaches a coastline. They make villages of model houses to test how different material types are impacted by the huge waves.
