# Calorimetry:Heat Exchange Hot Metal in Cold Water Computer Simulation

Calorimetry Computer Simulation is used to determine the heat exchanged in physical processes.   This computer simulation allows one to select the mass and initial temperature of various substance, put the substances in a calorimeter, and record the final temperature.

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
