Experiment #1: Determination of the Solid-Liquid Phase Diagram for Napthalene-Biphenyl Using Thermal Analysis Objective To apply thermal analysis to the two-component system‚ naphthalene-biphenyl at atmospheric temperature. The analysis will be represented by a solid-liquid phase diagram (freezing point diagram). Theoretical Principles Phase Equilibria and the Gibbs Phase Rule This experiment is conducted in order to study a condensed system (solid-liquid) at constant temperature (atmospheric

Johnny Lucio Is 4680 Lab # 4 1. What is a PHP Remote File Include (RFI) attack‚ and why are these prevalent in Today’s Internet world? RFI stands for Remote File Inclusion that allows the attacker to upload a custom Coded/malicious file on a website or server using a script. This vulnerability Exploits the poor validation checks in websites and can eventually lead to code Execution on server or code execution on website (XSS attack using JavaScript). RFI is a common vulnerability and all website

Objective: The objective of this lab was to find and examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity
