Temp. 25 C Pressure 76.0 Indirect Measurement of Volume INTRODUCTION: The purpose of this lab was to demonstrate an indirect measurement of volume. This was done by determining the volume of a single drop of using a graduated cylinder to measure a known amount of consistent drops‚ which allows for the individual volume to be determined mathematically. MATERIALS AND METHODS: Pipette‚ 10ml graduated cylinder‚ water‚ rubbing alcohol and hand soap. A pipette was used to place

Density‚ Mass and Volume Density is the measure of how tightly the particles of a substance are packed into a given volume. L=1cm B=1cm H=1cm Aluminium=1cm3 Volume=lbh Volume= 1cm*1cm*1cm Volume= 1cm3 Iron 1cm3 1cm3 of iron would be however than 1 cm of aluminium. The density of the iron cube would be greater than the density of the aluminium cube. One explanation from that is that the particles/molecules in the iron cube are more tightly

they weigh the same. What is this difference? The relationship between the lead and feathers is expressed by the physical property called density. Density is defined as the ratio of a substance’s mass to the volume it occupies. Density (g/mL) = Mass (g)___ Volume (mL) In this laboratory exercise‚ you will be using skills and techniques learned earlier to determine the identity of different substances. To determine the precision of your technique‚ you will calculate the

Molar Volume of a Gas – 10/27/08 Alic Albright‚ Josh Coleman‚ Dan Boden‚ Zach Babin Purpose: The pupose of this lab was to make an experimental determination of a molar volume through reaction of the substance shown: Mg(s) + 2HCl(aq) > MgCl(aq) + H(g) Introduction: In this lab‚ a magnesium ribbon and HCl are combined in a gas measuring tube. When they are combined they form magnesium chloride and Hydrogen gas. The molar ratio between Mg reacted and

Hercules: Character Variation There was one hero in ancient Greece who stood out the most; he was the strongest‚ the bravest‚ and the most god-like. Hercules was a favorite hero among men because he suffered and was therefore relatable. Through multiple sources the story of Hercules has been told: in Mythology‚ by Edith Hamilton (the most accurate version); in the History Channel’s 2009 episode‚ “Hercules” from the series‚ Clash of the Gods; in the 2014 movie Hercules directed by Brett Ratner‚ starring

1 Three Waves of Variation Study: The emergence of meaning in the study of variation Penelope Eckert Stanford University Abstract The treatment of social meaning in variation has come in three waves of analytic practice. The first wave of variation studies established broad correlations between linguistic variables and the macro-sociological categories of socioeconomic class‚ sex class‚ ethnicity and age. The second wave employed ethnographic methods to explore the local categories and configurations

It is used to express ideas and feelings close to one’s thoughts. The (L) variety is the first dialect that is taught to children as the mother tongue language followed by the (H) variety in schools. It is important however‚ to be able to distinguish between the context in which both the (H) and (L) varieties are used otherwise the individual is seen as a mockery. However‚ the ability to use both the (H) and (L) varieties in one speech community is acceptable as they can be used to complement each
