Investigate temperature in relationship to kinetic energy. 2.1	An excellent simulation by Noriyoshi Kato is called Billiards of Molecules (What's the difference in gas, liquid and solid) See Motion of Ideal Gas Molecules in a cylinder Kinetic Theory, Microscopic and Macroscopic Connections (a java applet) Equipartition Theorem (java applet) - The kinetic energy of a particle can be due to motion in the x, y, and z directions, as well as to rotations. The equiparition of energy theorem says that the kinetic energy of an atom or particle is, on average, equally distributed between the different modes (different degrees of freedom) available. Special Processes of an Ideal Gas - an applet to investigate ideal gases
Identify the characteristics of internal energy and temperature/heat (joules/calories). 2.2	Thermodynamic Equilibrium - an applet designed to simulate the diffusion process which occurs when gases of different temperatures are mixed (seven experiments can be performed with this applet) What is Heat? Methods of Heat Transfer Rates of Heat Transfer
Investigate changes in heat content (quantity of thermal energy) and relate to kinetic energy and specific heat. 2.3	What Does Heat Do? Measuring the Quantity of Heat Calorimeters and Calorimetry
Investigate potential energy changes (phase changes) of heat of fusion, heat of vaporization, and heat of sublimation [Change in Heat: ?Q= mHv and ?Q= mHv]. 2.4
Explore thermal expansion and contraction [Linear Expansion: ?l = li a?T ; Volumetric Expansion: ?V= Viß?T]. 2.5	Physics Lab: Linear Thermal Expansion - The purpose of this lab experiment is to measure the linear expansion coefficients of up to three different metals Thermal Expansion - explanation and illustration
Apply the second law of thermodynamics to the Carnot engine. 2.6
Apply the Laws of Thermodynamics to the atmospheric levels of the earth (i.e., greenhouse effect and global warming). 2.7
Recognize that absolute zero is the absence of molecular kinetic energy. 2.8
Relate the First Law of Thermodynamics as an application of the Law of Conservation of Energy and heat transfer through conduction, convection, and radiation. [Heat Lost = Heat Gained, QL= QG]. 2.9
Relate change in heat content (quantity of thermal energy) to kinetic energy and specific heat [Change in Heat: Q=mC?T]. 2.10
