The first law of thermodynamics is: “Whenever heat flows into or out of a system, the gain or loss of thermal energy equals the amount of heat transferred. The concentrations of products and reactants may change as a result of “equilibrium shifts” but the ratio of products to reactants as calculated using the equilibrium expression remains unchanged. This leads to the suggestion that at absolute zero, all substances have the some heat capacity. 1 Temperature and Thermal Equilibrium 2 Warm Up What is the difference between heat and temperature? Is there a difference? What makes something “hot?” This PowerPoint covers the following topics: specific heat capacity, calibrating a thermistor, heating ice, latent heats of fusion and vapourisation, particle motion in gases, pressure and volume in gases, pressure, temperature and absolute 1 Thermodynamics 2 A Little History In the 18th Century a theory was introduced that heat was a fluid (specifically a gas) The gas was called caloric Caloric flowed from hot objects to cold The laws of thermodynamics are explained in terms of microscopic constituents by statistical mechanics. this presentation involves an introduction of carnot cycle its working and applications in daily life. Thermodynamics is the study of energy relationships involving heat, work, and 9. AP Physics Chp 15. Therefore, the total energy of the universe is a constant. Temperature Temperature is the measurement of degree of hotness or coldness of a body i. The first law of thermodynamics is a form of conservation of energy which takes into account a system’s internal energy. Heat is measured in Joules (J). S=0 at T = 0 K • If the particles of a crystalline solid are perfectly aligned and in their lowest possible energy states, the crystal has only one microstate, therefore, entropy is zero. 4 Heat, internal energy and work 11. 4 Thermodynamic and Kinetic Control (slides 50-55) 9.

There are various instruments for Objectives Introduce the second law of thermodynamics. 1 of 9. Next think about heating up 1,000 cups of coffee to 100°C. Food drying for reservation f. A Carnot engine uses a single-phase working fluid thus for a properly designed system the risk of explosion is low. It has applications in engines and power generation. THERMODYNAMICS: the science of energy, specifically heat and work, and how the transfer of energy effects the properties of materials. AP Chemistry follows the CED from the College Board. Thermodynamics class 11 physics.
