Plan. Why Changes Take Place Temperature, Thermal Energy and Heat Law of Conservation of Energy Energy Units Heat Capacity and Specific Heat Measurement of Thermal Energy Changes Enthalpy Hess’s Law. Dang Saebea. The first law of thermodynamics – all of the energy is the universe is conserved. Can a reaction occur? First Law of Thermodynamics: energy is conserved Any process that occurs without outside intervention is spontaneous Dropped eggs spontaneously break. 6 Chemical Thermodynamics Science of interconversion of energy Heat into other forms | PowerPoint PPT presentation | free to view Aug 14, 2014 · Chemical Thermodynamics. - Systems, surroundings, boundaries, closed/open/isolated systems, and state functions like internal energy are defined. AP Chapter 19. 1. Jan 30, 2013 · Chemical Thermodynamics. 5, 19 How fast will the reaction occur? Ch. The zeroth law of thermodynamics deals with thermal equilibrium and provides a means of measuring temperature. 60) Chemical Engineering Thermodynamics (10. The total energy of the universe is a constant. Homework and Exams. First Law of Thermodynamics Energy is Conserved – ΔE = q + w Need value other than ΔE to determine if a process if favored (spontaneous) Spontaneous processes have a direction Spontaneity can depend on temperature. 4 Gas Molecules Relative Probability. 15 Chemical Thermodynamics The chemistry that deals with the energy and entropy changes and the spontaneity of a chemical process.
