Title: Density‚ Alcohol Content and the Archimedes Principle (Performed 09/11/13) Report submitted by: Purpose: Part I was to examine three different objects of the same material in order to identify the type of metal. We used the water displacement method and the buoyancy method according to Archimedes Principle. Part II was to find the density of ethanol by mass. We used a 25.0mL graduated cylinder and a 25.00mL volumetric flask to measure the volume. We used two different pieces of glassware

Sugar Solution vs. Average Density The objective of this lab was to determine the percent (by mass) of sugar in a non-carbonated beverage by measuring its density and using calibration curving showing the density and concertation of standard solution. The procedure used in this experiment was 2 50mL beaker and 10-mL volumetric pipet & pipet pump. 40 mL of deionized water was poured into a 50 mL beaker. Then 10 mL of that deionized water (0% sugar solution) was pipet‚ using the volumetric pipet

Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Nancy ng (effects) As a student‚ there is no excuse for us to be late for school. Being late is not acceptable. It’s because late arrival not only affects the person‚ but also other people. For the person who is late‚ he/she will miss the morning assembly. There may be some important announcement and he/she will not know it. If late arrival becomes a habit‚ the effects will be more serious. Workers may easily lose their job if they aren’t punctual. Lateness can also affect other people.

Should women be permitted to work late night shifts? Shift work is a planning strategy designed for organizations that operates in constant service for twenty-four hours‚ which includes late night shifts that begin after seven o’clock in the evening and finishing before nine o’clock in the morning. Due to the nature of this type of work‚ it becomes problematic for women to work late night shifts. Information for this essay has been obtained through secondary research using websites and electronic

We have received so many questions about this problem that we know it is crying out for a solution. So many people are wasting so much time in staying up late at night. But the truth of the matter is that this phenomenon is not homogenous. There are three kinds of staying up late: (1) Staying up late to worship Allaah. This is the worthy kind of staying up. It includes staying up for reasons that are of benefit to the Muslims in general‚ such as staying up to pray (qiyaam al-layl) and read Qur’aan

Reflections of Late Adulthood and Ego-Integrity Kristy Bazzanella Liberty University Abstract This report examined empirical articles which investigated Erikson’s eight and ninth stages of psychosocial development and endeavored to find answers to varying postulations of his theories; does development and growth continue in the later stages of human development‚ and if so‚ what type of growth is it; additionally is this growth stunted or enhanced by the way we resolve our conflicts between
