Lab 02: Lighter Than Air? A Density Study Date Performed: 09/08/2014 Date Submitted: 09/16/2014 Mariel Allegra Del Valle 1/6 Lab 02 - Lighter than Air? A Density Study: Lab 02: Lighter Than Air? A Density Study Del Valle‚ Mariel Allegra Abstract This experiment is composed of three parts. The purpose of the first experiment is to find the density of dry ice by using the method of displacement volume. Before the experiment‚ it was thought that the density would decrease over time

Why will insulators affect how long a test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube‚ shiny foil can be used because it’s a poor emitter of radiation and it will reflect escaping heat by reflecting‚ because this method is used in flasks to keep hot drinks warm. Though it is a good conductor so will lose heat through to surfaces its touching but it shouldn’t matter because it will be touching air and glass which both

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

By measuring the concentration of the hydroxide ion from a solution saturated with Ca(OH)2 titration analysis against HCl‚ the experiment’s objective is to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant. -------------------------------------------------

The Milgram Experiment Stanley Milgram‚ a famous social psychologist‚ and student of Solomon Asch‚ conducted a controversial experiment in 1961‚ investigating obedience to authority (1974). The experiment was held to see if a subject would do something an authority figure tells them‚ even if it conflicts with their personal beliefs and morals. He even once said‚ "The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation
