Summary

Thermal Analysis

The branch of material science known as thermal analysis is the study of the change of temperature within the properties of materials. A number of different properties are studied using this method including mass, dimension, volume, stiffness, damping, heat transfer and temperature. Other concepts can be employed within the method as well, determining how temperature relates to light and sound. The main purpose of the entire discipline is to find how temperature impacts other facets of physics.

When conducting experiments with thermal analysis, researchers generally control the temperature in a standardized format. This is accomplished by either keeping, increasing, or decreasing the temperature at a constant rate or working with a variety of predetermined different temperatures. Adjustments can be made for different research techniques using oscillating temperatures.

Environment is also a major key in properly conducting thermal analysis. The atmosphere surrounding and permeating the element being researched can have drastic effects on the technical results. Some of the most common environments in which to study thermodynamics include general air or an inert gas such as nitrogen or helium. This allows the least impact on the results of heat transfer and other elements within the study.

The thermal analysis of polymers is one of the largest areas of research within the field. This comes in the form of both raw materials as well as everyday packaging and household products. Raw materials can be studied with the addition of various elements such as dyes and stabilizers to determine what may be the best use for the materials. Packaging and products

    This report discusses an investigation of the heat capacities of Helium, Nitrogen, and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas, the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each gas. The apparatus consisted of a Kundt 's tube, an osilliscope, a ruler, an audio oscillator, and a frequency counter. The experimental values of heat capacity were found to agree with the theoretical values within the range of uncertainty. This experiment conclusively demonstrated an accurate method of determining the heat capacity of a gas.…

    Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both, the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one.…

    The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric, area, and linear. This is used depending on the particular application and which dimensions are considered important. For solids, one might only be concerned with the change along a length, or over some area.…
