PPT-Chapter 9: Heat

Section 91 Temperature and Thermal Equilibrium Defining Temperature Temperature a measure of the average kinetic energy of the particles in a substance Adding or removing energy usually changes temperature. trantercom GASKETED AND WELDED HEAT EXCHANGERS FOR EVERY NEED brPage 2br Gasketed Plate Heat Exchangers Tranter provides the worlds largest range of Plate Heat Exchangers PHEs for a variety of applications 57375e PHEs are built on a modulebased conce Scales of Measurement. Celsius scale – based on where water freezes (0. . C) and where water boils (100. . C). Kelvin scale – based on the movement of particles. . Absolute Zero. At 0 K, all particle movement has ceased. 3.1 …………. Introduction. 3.2 …………. Biot and Fourier Number. 3.3 …………. . Lumped heat capacity analysis. 3.4 …………. Time constant and response of a thermocouple. 3.5 …………. Transient. Chapter Outline . Heat as energy transfer. Temperature vs. heat vs. internal energy. Internal energy of an Ideal Gas. Specific Heat. Calorimetry. Latent Heat. Heat Transfer: conduction, convection, and radiation. How does heat energy get from the Sun to the Earth?. There are no particles between the Sun and the Earth so it CANNOT travel by conduction or by convection. . ?. RADIATION. How can we relate our new understanding to the greenhouse effect?. is often used specially to denote equipment in which heat is exchanged between two process. Streams.. These heat exchanger may be classified according to:. Transfer process. 1. Direct contact. 2. indirect contact. Section 16.1 – Thermal Energy and Matter. In the 1700’s most . scientists. thought that . heat. was a . fluid. called . caloric. that flowed between objects.. Count Rumford. Rumford. studied the process of . HEAT? TEMPERATURE?. How to measure temperature?. How to quantify temperature and heat?. How do heat transfer?. HEAT & TEMPERATURE. Temperature. is a quantitative measurement of . hotness/coldness. June 6, 2017.
