PPT-Introduction to the Second Law of Thermodynamics (on board)

Heat engine A cyclic heat engine Thermal efficiency Examples of heat engines a simple steam power plant Refrigerators and heat pumps Refrigerator is a device which operating in a cycle maintains a. 1. st. law of thermodynamics. Energy may be converted to different forms, but it is neither created nor destroyed during transformations. Energy from chemical bonds is converted to kinetic energy and heat (body and friction from tires). No engine, working in a continuous cycle, can take heat from a reservoir at a single temperature and convert that heat completely to work.. Therefore, no engine can have a greater efficiency than a Carnot engine operating between the same two temperatures.. AP Environmental Science. What is Energy?. Energy is a . measurable quantity. that can be stored in a physical system. Energy can be . transferred. from one system to another and so . cause changes. Change of phase . . ice. .  . water.  . steam. The Laws of Thermodynamics. The 1. st. Law. The 2. nd. Law. Applications. Heat engines. Refrigerators. Order to disorder. 2. Change of Phase. The Basics. The brief definition of Thermodynamics is . the science concerned with the relations between heat and mechanical energy or work, and the conversion of one into the other: modern thermodynamics deals with the properties of systems for the description of which temperature is a necessary coordinate. Principles of . Engineering. 1. Thermodynamics. Rub your hands together for 15 seconds.. Are your hands warm?. Thermal energy. 2. Thermodynamics. The study of the effects of work, heat flow, and energy on a system. ~Energy. Intro. Most natural events involve a decrease in total energy and an increase in disorder.. The energy that was “lost” was converted to heat. . An increase in energy/motion decreases the overall order (organization) of the system.. © 2014 Pearson Education, Inc.. Contents of Chapter 15.
