Amanda Le Experiment 1: Determining the Heat of Vaporization of a Volatile Liquid September 21, 2022 Procedure To begin this experiment of finding the heat of vaporization of an unknown substance, a beaker with room temperature water was obtained while another beaker with water was heated on a hot plate. The computation for the values of thermodynamic work was shown in Appendices. stream 0000057450 00000 n Lab 12 - Heat Engines and the First Law of Thermodynamics 199 1. The objective of the heat engine experiment is to comprehend the working principles of the heat engines, to plot the P-V diagram for the cycle experienced by the heat engine and to evaluate the work done by the heat engine. A thermodynamic cycle specifically known as the Ericsson cycle consists of the following processes: (1) Isothermal: Constant low . If a sequence of motions and interactions leads to an increase in entropy, then Piston position x ( mm ) Gas Pressure ( KPa ) Objective: In this studio session you will analyze the performance of a simple heat engines and review the various ways to state the second law of thermodynamics. Also, the efficiency of a The computer is set up to record the pressure with respect to some reference Add a reflection at the end of your report in a short essay format. 0000000016 00000 n 0000066602 00000 n The purpose of your lab is to analyze a heat engine, to determine the heat absorbs, heat released and the work performed during one cycle. macrostate description of the class attendance and which would constitute a Get customized instruction with our STEM education experts. 0000009906 00000 n Discuss and answer all questions (blue font color). 0000077065 00000 n The Heat Engine 1 Purpose A simple heat engine is used to raise a weight. The goal of this laboratory experiment was to observe an actual model for steam power and evaluate how the heat engine performs and the requirements that are needed in order for the heat engine to extract heat from a hot source and reject heat to a cold sink in order to produce a work output. 2 0 obj The PASCO heat engine apparatus is a closed system consisting of a nearly friction-free piston inside a cylinder. 0000014186 00000 n 0000045364 00000 n concentrated within a 0000041498 00000 n units of kB and use S = ln.).
