Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

’Spring’ ’How does Hopkins use language and style to convey his message to his readers?’ Gerard Manley Hopkins was a 19th-century poet whose poetry work mainly consisted of religion‚ nature and inner anguish as the main themes. Hopkins celebrated beauty in the nature world and he loved the season of spring‚ especially the freshness it brought. In most of his poems‚ like ’Spring’‚ Hopkins linked in nature to prayer and religion; he thought that the pure beauty in nature alone‚ was enough

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

Most of performers have great instrument skill and show us a wonderful music. Each movement highlights the character‚ range‚ and technical abilities of an individual instrument‚ all of pieces stand on their own as intricate musical gems. The show was divided for two parts‚ and they have different

experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid‚ gas or solid) by the use of only a select few measurements and the formulae contained herein. Introduction In observing oil floating on water one unknowingly observes a difference in

flatworms due to their embryonic stem cells called neoblasts. We obtained the flatworms used in this experiment by first placing a few drops of spring water on a petri dish so that the flatworms will be able to survive a couple of weeks‚ and not be dehydrated. Next‚ we used a pipette to gather the flatworm and then placed the worm on the petri dish‚ with the spring water. Using a razor blade‚ the worm was cut in half into two sections of 6mm in length and 5 mm in length. The worms were measured using a

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy
