Segment H: Chemical Thermodynamics Review
Segment H: Chemical Thermodynamics Review
Our host recaps Unit 8, "Chemical Thermodynamics.” The unit covered the three laws of thermodynamics and introduced students to thermochemistry. Total Bond Energy was covered, as well as specific heat capacity.
Science
Obtain, evaluate, and communicate information about the chemical and physical properties of matter resulting from the ability of atoms to form bonds.
Develop a model to illustrate the release or absorption of energy (endothermic or exothermic) from a chemical reaction system depends upon the changes in total bond energy.
Obtain, evaluate, and communicate information about how the Law of Conservation of Matter is used to determine chemical composition in compounds and chemical reactions.
Plan and carry out an investigation to determine that a new chemical has been formed by identifying indicators of a chemical reaction (e.g., precipitate formation, gas evolution, color change, water production, and changes in energy to the system).
Obtain, evaluate, and communicate information to explain transformations and flow of energy within a system.
Plan and carry out investigations to describe how molecular motion relates to thermal energy changes in terms of conduction, convection, and radiation.
Analyze and interpret specific heat data to justify the selection of a material for a practical application (e.g., insulators and cooking vessels).
Analyze and interpret data to explain the flow of energy during phase changes using heating/cooling curves.
Obtain, evaluate, and communicate information about the law of conservation of energy to develop arguments that energy can transform from one form to another within a system.
Plan and carry out investigations on the effects of heat transfer on molecular motion as it relates to the collision of atoms (conduction), through space (radiation), or in currents in a liquid or a gas (convection).
