Essays on Aluminum Foil

Abstract

In this experiment, two calorimeters were designed and assembled. One was made using Styrofoam cups and another one using glass and foil. The calorimeters were studied for their performance in keeping the heat of the system. They were studied by measuring the heat loss of hot water over time. The heat lost in each calorimeter over 30 minutes was calculated. The calorimeter made of glass worked better and less heat was lost in it. The assembled calorimeters were used to find out the heat of reaction between NaOH and HCl per one mole of water. This value was found ...

My sister has always been asking me how I manage to make the perfect lasagna. She is an inpatient person, and I needed to explain to her that the one ingredient that cannot be bought is love towards food. Lasagna is a wonderful dish that needs a little knowledge but a lot of effort and time in order to prepare it perfectly. In my case of lasagna preparation, around three hours is needed. Lasagna can be prepared faster but it will never be perfect as it is served in an Italian restaurant. I will go step by step so that my sister ...

Introduction

This lab experiments was to see how light travels through the pin hole camera to form images. This was achieved through a number of steps. The basic functional principle of a pin-hole camera is that, when a shutter is opened-in this case a small pin hole, light that bounces off objects and is directed through the hole, an image is formed on a screen that is on the other side of the hole. However, this image appears to be inverted. Since the pin hole is very small, the light rays that pass through it will not overlap. This is the reason for the formation ...

Introduction

Alum is a double salt that is obtained from aluminum. It is used in pickling process and the dying of various fabrics by recycling aluminum useful products can be obtained from previous material generally regarded as refuse.

Materials

Aluminum foil, aqueous solution of KOH Procedure Dissolve aluminum foil in hot aqueous solution of KOH. The solution will acidify until a precipitate will be recovered (alum) Re-crystallize the precipitate to eliminate impunities. Results Group 1 - Na + O2→Na2O2 - Na2O2 +2H2O→H2O2+2NaOH - Cesium would be more reactive than sodium.

Group 2

- 2Mg + ...

Background information

TV is viewed as an important component in most households. Watching television is one of the most affordable forms of entertainment.
