The students discover the basics of heat transfer in this activity by constructing a constant pressure calorimeter to determine the heat of solution of potassium chloride in water. They first predict the amount of heat consumed by the reaction using analytical techniques. Then they calculate the specific heat of water using tabulated data, and use this information to predict the temperature change. Next, the students will design and build a calorimeter and then determine its specific heat. After determining the predicted heat lost to the device, students will test the heat of solution. The heat given off by the reaction can be calculated from the change in temperature of the water using an equation of heat transfer. They will compare this with the value they predicted with their calculations, and then finish by discussing the error and its sources, and identifying how to improve their design to minimize these errors.

Harnessing energy from heat changes to solve a problem - Version 2

Using inquiry-focused reading, students will explore an anchor text and supporting resources to investigate the principles of transfer of heat energy with applications of the concept to solve real world problems.
The instructors will prepare a sample presentation and model for students the steps taken to go from a text to the final project. Students will learn annotations, two column notes, and citations, while learning about how chemistry is used to solve real world problems based on the instructor provided materials. The students will then apply those concepts to a different project assigned by the instructors and apply the same strategies to their own texts to demonstrate their application of learning to a different problem.
Over the course of the unit, students will explore a variety of resources to develop their knowledge of heat energy changes that accompany physical and chemical reactions, measurement of heat energy, and heat energy transfer between the system and the surroundings. They will expand their ability to use informational text to support their inquiry and research, explore scientific literature, and develop questions to determine how the application of energy transfer principles can be applied to solve real world problems.

In this course, the student will learn about the three laws of thermodynamics, thermodynamic principles, ideal and real gases, phases of matter, equations of state, and state changes. The student will also take a look at chemical kinetics--a branch of study concerned with the rates of reactions and other processes--as well as kinetic molecular theory and statistical mechanics, which relate the atomic-level motion of a large number of particles to the average thermodynamic behavior of the system as a whole. Upon successful completion of this course, the student will be able to: State and use laws of thermodynamics; Perform calculations with ideal and real gases; Design practical engines by using thermodynamic cycles; Predict chemical equilibrium and spontaneity of reactions by using thermodynamic principles; Describe the thermodynamic properties of ideal and real solutions; Define the phases of matter, describe phase changes, and interpret/construct phase diagrams; Relate macroscopic thermodynamic properties to microscopic states by using the principles of statistical thermodynamics; Describe reaction rates and then do calculations to determine them; Relate reaction kinetics to potential reaction mechanism; Calculate the temperature dependence of rate constants and relate that to activation energy; Describe a variety of complex reactions; Describe catalysis; Describe enzymatic catalysis.
