Thermodynamics of the Dissolution of Borax Lina Jawadi Objectives: * Study a system of salt and water solution. * Determining a variety of important thermodynamics quantities from the solubility information at various temperatures. Background: The salt and water solution in this experiment has relatively simple solubility equilibrium of borax in water. Na2B4O7 . 10 H2O 2Na + + B4O5(OH)42- + 8H2O This reaction is an equilibrium

1-1 Chapter 1 INTRODUCTION AND BASIC CONCEPTS Thermodynamics 1-1C Classical thermodynamics is based on experimental observations whereas statistical thermodynamics is based on the average behavior of large groups of particles. 1-2C On a downhill road the potential energy of the bicyclist is being converted to kinetic energy‚ and thus the bicyclist picks up speed. There is no creation of energy‚ and thus no violation of the conservation of energy principle. 1-3C There is no truth to his claim

THERMAL EQUILIBRIUM AND TEMPERATURE Two systems are said to be in thermal equilibrium with each other‚ if they are at the same temperature. ZEROTH LAW OF THERMODYNAMICS It states that if two systems A and B are in thermal equilibrium with a third system C‚ then A and B must be in thermal equilibrium with each other. Fig. 1.01 shows two systems A and B separated by an adiabatic wall (a wall which does not allow hear flow).The two systems are placed in contact

statistical thermodynamics[note 1] is a branch of physics that applies probability theory‚ which contains mathematical tools for dealing with large populations‚ to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life‚ therefore explaining thermodynamics as a result

Gas laws have an impact on several aspects of our lives. The S.T.E.M I decided to explore deals a great deal in thermodynamics in the gas law I chose chemistry. First off I have to explain what is the broad practice of chemistry. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with

I did not understand how to explain why temperature does not change during a phase change and am not entirely sure if I have accurately or thoroughly described 3.2.3 and 3.2.4. This is also the case for 3.2.12 Thermal Physics Thermal Concepts: Temperature (T) is a measure of how hot or cold an object is‚ and it is the temperature that determines the determines the direction of thermal energy transfer between two objects. It is a scalar quantity and is measure in degrees celcius (°C
