If you are a chemistry instructor (high school, AP Chemistry, or college) using this Flash-based computer simulation in your chemistry classroom, please consider making a voluntary donation to the University of Oregon Foundation "Chemistry Achievement Endowment Fund".  Because Flash will soon no longer be supported by browsers, we need funding to convert this simulation to a HTML5 based computer code.  There is a letter explaining the situation and a "donate" link on the home page of this "chemdemos" web site and on TG's UO web page:

Curriculum Notes 

Learning Objectives

1. Use experimental data to develop a conceptual understanding of the First Law of Thermodynamics and how to apply it to calorimeter experiments:

lost + q gain = 0   The transfer of energy from a hot object (metal) to a cool object (water).

2.  Ask a research question and design a series of experiments to provide data to answer the research question.  

3. Use experimental data to develop a relationship among the variables: heat, mass, specific heat, and change in temperature.

4.  Identify what gains heat and what loses heat in a calorimetry experiment.

5.  For a physical process explain how heat is transferred, released or absorbed, at the molecular level.

6. Calculate the heat released by a sample of hot metal, qloss, involved in a given calorimetry experiment: mass of the metal, specific heat of the metal, change in temperature of the metal: qloss = m c ∆T   

7.  Calculate the heat gained by a sample of cool water, qgain, involved in a given calorimetry experiment: mass of the metal, specific heat of the water, change in temperature of the water:  qgain = m c ∆T 

8.  Calculate the specific heat of a sample of metal, given: mass of the metal, change in temperature of the metal, mass of the water, specific heat of the water, change in temperature of the waterqloss = m c ∆T     qgain = m c ∆T 

Learning objective 5.7 The student is able to design and/or interpret the results of an experiment in which calorimetry is used to determine the change in enthalpy of a chemical process (heating/cooling, phase transition,
