ABSTRACT: In total three experiments were conducted to familiarize the laws of thermodynamics, the concepts of enthalpy and entropy, Gibbs free energy and its relation to spontaneity, and energy st... orage. Each experiment tackled different concepts and this was implemented via the labster learning resource. The first experiment posed the problem of transporting solar energy over long distances and investigated the most efficient way of storing energy in doing so. The second experiment used the combustion of octane in a system to determine its energy content. It showed the relation between enthalpy and the internal energy of the system. The third experiment used the transformation of reactants carbon dioxide and molecules of water into products of propane and oxygen to discuss the enthalpy and entropy of a reaction in terms of Gibbs free energy. These experiments reveal important concepts in energy conservation and the most efficient storage material to be utilized in doing so. The concepts of enthalpy and entropy and spontaneity in Gibbs free energy are important supplementary concepts to learn in solving the challenge being posed. INTRODUCTION: Objectives: learn about the laws of thermodynamics(1), the very important concepts of enthalpy and entropy(2) and how to use the Gibbs free energy to determine whether a reaction will occur spontaneously or not.(3). Investigate which would be the most efficient way to store energy(4) The first experiment is meant to investigate the problem of conserving solar power in the most efficient way possible and transporting it at long distances. The experiment familiarized the law of conservation of energy and the most efficient means of energy storage based on specific energy and energy density. It continued by tackling the most relevant forms of energy storage for long term given the problem being posed. The combustion of 1.00 gram of octane was an experiment used to show the relation between the enthalpy and the internal energy of the system. The heat energy given out by the system is indication of the enthalpy of combustion and this was measured by the bomb calorimeter.
