Curated OER
Heating/Cooling Curve
In this heating and cooling curve activity, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the substance and the...

More Thermochemistry Problems
This two-page assignment covers basic thermochemistry concepts. Chemistry learners identify exothermic and endothermic processes, explain a phase change graph, and draw an energy level diagram. There are no problems to solve, just...
Curated OER
Phase Transition Temperature of Fats
In this chemistry instructional activity, students investigate through experimentation the solidifying behavior of some edible fat mixtures by determining their cooling curves. Then they data-log equipment to obtain a large number of...
