Document Summary
3rd of may 2012 10-12am session group members: daniel, henry and luke. Part a: to measure the heat output generated by an electrical current. Part b: to rank various materials in decreasing order of thermal conductivity so as to appreciate which materials are good and which are poor conductors. Part c: to examine the rate of cooling of a hot object. Energy is defined as an objects ability or capacity to do work [1]. Energy exsists as many different forms throughout the universe such as heat, sounds, kinetic, potential, chemical and many more. The law of conservation of energy states that energy cannot be created nor destroyed but instead only transformed from one energy type to another [2]. Heat is one form of energy related to the movement of atoms and molecules within an object. It is capable of being transferred through liquids, gases and solids by conduction, convection or radiation.
