Liu1 Experiment 8: Calorimeter ? the science of measuring Heat Objective: The objective of this experiment is to determine the specific heat capacity of an unknown metal and the heat of solution for the salt. Method: A calorimeter is a device used for calculate the enthalpy change of reaction, the science of measuring the heat of chemical reactions or physical change as well as heat capacity. The heat capacity of an object is the amount of heat needed to raise the temperature by 1K (or 1?C). The heat capacity of one gram of a substance is called its specific heat capacity.

Chemistry 1210: Introduction to General Chemistry Dr. Gina M. Florio 18 October 2012 Brady, Jespersen, Hyslop Chapter 7 Energy & Chemical Change Thermochemistry: the study of energy flow during a chemical reaction Ch. 7.1 Energy: the ability to do work; often measured as heat Kinetic Energy: the energy of motion; KE = ?mv2 Potential Energy: stored or positional energy; chemical energy (no simple eqn.) Conservation of Energy: 1. Energy cannot be created or destroyed 2. Energy is only converted from one form to another (KE ? PE) 3. Total energy of the universe (or an isolated system) is constant Thermochemistry: Basic Definitions Units of Energy 1 Joule (J) ? the KE possessed by a 2 kg object moving at a velocity of 1 m/s 1 cal = 4.184 J (exactly) 1 kcal = 4.184 kJ

Chapter 5: Thermochemistry ?Introduction- Energy is defined as the capacity or the ability the to do work i.e. in order to do work energy must be involved Mathematically Represented- Work or Energy = Force x Distance The view of energy can be thought of as physical in nature and contact via the exerted force Chemistry, however, must view energy differently. The study of energy and its transformation, as it applies to chemistry, is know as THERMOCHEMISTRY, along with spontaneity, the two are referred to as THERMODYNAMICS Section 5.1- Nature of Energy The study of chemistry and thermodynamics will involve the concepts of energy, work, and heat KINETIC and POTENTIAL Energy Kinetic ? energy due to an objects motion
