Sulfuric Acid into Water and Ice When sulfuric acid is mixed with water the temperature rises. When sulfuric acid is added to ice, the temperature rises at first, but as the ice melts, the temperature falls.
Thermochemistry : SystemSurrExoEndo (4 Variations)
Sulfuric acid is added to water in a beaker and the resulting solution is much warmer than either the water or acid was initially.
Identify the following items as being part of the system or the surroundings, and indicate whether the process is exothermic or endothermic.
[#94] Hold the Heat: Global Heat Retention, Global Warming and CalorimetryJoel D. Burley and Harold S. Johnston Students perform quantitative calorimetric measurements on samples of ice/water heated by incandescent light bulbs and by convection with room-temperature surroundings. Burley, Joel D.; Johnston, Harold S. J. Chem. Educ.2008, 85, 224A.

Real-World Topics: Medicinal ChemistryArrietta Clauss Instructors often look for real-world topics that interest students when designing labs and preparing lectures. The chemistry associated with drugs is a fertile area, and the archives of the Journal can be a resource for interesting drug-related activities to enhance student learning. Clauss, Arrietta. J. Chem. Educ.2008, 85, 1657.

Molecular Models of Polymers Used in Sports EquipmentWilliam F. Coleman The Featured Molecules this month are a number of monomers and their associated polymers used in making equipment for a variety of high-impact sports. The molecules provide students with an introduction to an important area of applied chemistry and also enable them to examine complex structures using the models they have seen applied to small molecules. Coleman, William F. J. Chem. Educ.2008, 85, 1456.
