Lab Report 3: Electrical Properties of Ceramic Materials Lab III: Physical Properties of Materials By Will Paxton 3/5/07 Abstract The electrical properties of 5 different samples were studied. Characterization of these samples was through the dielectric properties‚ as this is a very important step. The capacitance was measured for each sample incrementally while heating them up to 135ºC. In a second part to the experiment‚ piezoelectric samples were studied‚ and their piezoelectric coefficient

TERMPAPER TOPIC:- imperfection in solid’s NAME:-MILAN RAJAWAT Regd. No.:-11004886 Section:-M2R16 Roll No.:-B16 Subjet:-MEC208 INTRODUCTION For a crystalline solid we have tacitly assumed that perfect order exists throughout the material on an atomic scale. However‚ such an idealized solid does not exist; all contain large numbers of various defects or imperfections. As a matter of fact‚ many of the properties of materials are profoundly sensitive to

flask‚ (3ml) of propanol was added‚ heated and cooled. Filteration was tried once more to gain crystals. Due to nonexistent crystals a melting point could not be performed. Observations: We noticed after adding propanol our solution became very orange and cloudy. After heating it the solution was a clear golden color. We chilled the solution in ice and attained no crystals. After repeatedly heating and cooling‚ we saw our solution go from cloudy to clear over and over

After doing this‚ we allowed the solution to cool to room temperature before placing it in an ice bath to form crystals. About 15 minutes after placing the solution on ice‚ small‚ white-colored crystals began to form on the bottom of the solution. We then performed a vacuum filtration using the Buchner funnel‚ allowing us to separate the crystals and the solution. After the crystals were filtered out of the solution‚ we dried and weighed them. In order to determine the melting point of our unknown

“water stream” breaks. The motivation for choosing this topic was the first demonstration of total internal reflection carried out by Colladon and Babinet in Paris in 1840s1. Titled as “On the reflections of a ray of light inside a parabolic liquid stream ”‚ it was published in 1842. The paper was based on the description of a “light fountain”. Using the optical characteristic of water‚ they observed the behaviour of the light when it propagates inside the water stream

Hypothesis: If...‚ then... Materials: 1. 2 Plastic cups 2. Tap Water 3. Teaspoon 4. Bag of salt 5. Freezer 6. Clock 7. Paper 8. Pencil Procedures: 1. Take plastic cup and pour in one cup water in each 2. Take one teaspoon of salt and mix it in one of cups 3. Put both cups in the freezer 4. Observe. Conclusion: When salt is added to water it slows the freezing process down‚ therefore the freezing point of tap water is higher than the freezing point of salt water

with 1.5 grams of the impure acetanilide solute and ended the lab with 0.05 grams of pure acetanilide crystals. The percentage of pure acetanilide I recovered during this lab was 3.33%‚ which is lower than I expected. However‚ the low percentage shows that the impurities within the original impure acetanilide solute were removed. A number of factors could have caused the low yield of pure crystals. The melting

is to compare the different densities of different liquids. Density is a comparison between an object’s mass and volume. Density = Mass divided by Volume. If the weight (or mass) of something increases but the volume stays the same‚ the density has to go up. If the mass decreases but the volume stays the same‚ the density has to go down. This experiment will show how the weight of certain liquids react to each other. Page 3 The seven liquids I have chosen for the experiment have different weights
