Flows from highertemperature object to lowertemperature object System T 1 Surroundings T 2 Heat If T 1 gt T 2 q system exothermic System T 1 Surroundings T. 4.1 …………. Introduction and Types of Fins. 4.2 …………. Governing Equation of Fin. 4.3 …………. Heat Dissipation through Rectangular Fin. 4.4 …………. Heat Dissipation from Infinitely Long Fin. Heat Energy. Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. Fins and Extended Surfaces. 1. Chapter 3c : One-dimensional, Steady state conduction (with thermal energy generation) (Section 3.5 – Textbook). 2. 3.1 Implications of energy generation. Involve a local source of thermal energy due to conversion from another form of energy in a conducting medium.. . conduction. c. onvection. radiation. Energy can be transferred from one system to another (or from a system to its environment) in different ways: . Thermally. , when a warmer object is in contact with a cooler . Section 9.1: 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. 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.

Defining Temperature. Temperature: a measure of the average kinetic energy of the particles in a substance. Adding or removing energy usually changes temperature. Internal Energy: energies associated with atomic motion. 1. = T. 2. . . The most common is Celsius temperature scale. T= 0. o. C is the melting point of ice, and T= 100. o. C is the boiling temperature of water at atmospheric pressure.. Many properties of matter depend on temperature. For most substances, volume increases upon heating (exception: water near freezing point, between 0.
