as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

Dependencies and Network Diagram The network diagram is a schematic representation showing the sequence and relationship/ dependency of the tasks along with their duration. All the tasks‚ except the first and the last‚ are linked with at least one predecessor and successor to have a proper sequence of work. This logical dependency between the tasks will determine afterwards the duration of the project. There are four types of dependencies which define the relation between pair tasks Finish-to-start

Circular Flow Diagrams Introduction Money flows into and out of the economy. The circular flow diagram explains how money moves through the economic system involving households‚ businesses‚ the government‚ and foreign agents (Editorial Board‚ 2011). Circular flow diagrams are visual models that show firms who employ workers‚ the workers then spend on goods produced by firms‚ and the money is then used to compensate the worker and buy raw materials to make the goods and the circle continues.

The Hertzsprung-Russell Diagram or‚ the H-R Diagram for short‚ is a graph which plots stars according to their temperature and absolute magnitude. This graph reveals a pattern‚ which in fact is quite interesting. The H-R Diagram is named for the two astronomers‚ Ejnar Hertzsprung and Henry Russell‚ who discovered this pattern of stars. These two astronomers independently discovered that comparing magnitudes and spectral class (color) of stars yielded a lot of information about them. <br><br>One key
