The Use of Cooling Curves in the Determination of the Phase Diagram for a Lead-Tin System V.O.L.Tabell Department of Mining‚ Metallurgical and Materials Engineering University of the Philippines‚ Diliman vo_tabell@yahoo.com Abstract This paper discusses the use of the cooling curves in the determination of the phase diagram of a Lead-Tin system. The inflection points of these cooling curves were obtained by melting a series of mixtures of lead and tin at varying compositions. These critical

Assignment: Draw and explain a Use-Case diagram for a Library Management System. Introduction: Capturing the dynamic behaviour of a system is one the key aspects to create a model. Dynamic behaviour means the behaviour of the system under operation. Use case diagrams are used in Unified Modeling Language‚ a standard modelling language for the modeling of real-world objects and systems. A use case diagram is to explicitly define the working of a system with in a system boundary. Each system is primarily

Venn diagram –Max-min 1. According to a survey‚ at least 70% of people like apples‚ at least 75% like bananas and at least 80% like cherries. What is the minimum percentage of people who like all three? Answer: Let’s first calculate the surplus: percentage of people who like apples + percentage of people who like bananas + percentage of people who like cherries = 70% + 75% + 80% = 225% = a surplus of 125%. Now this surplus can be accommodated by adding elements to either intersection of only

for a molecule or ion‚ follow these steps: •Step 1: Count up the number of valence electrons for each atom‚ and total them up to give the total number of electrons for the molecule. If the molecule is an ion‚ include that charge in the count. For example‚ for a +1 ion‚ subtract one electron‚ and for a -2 ion add two electrons to the total count. (For more information about how to count the number of valence electrons per atom‚ see the related questions link to the left of this answer). •Step
