1.) How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? The way the fluted filter paper is folded hastens filtration because it increases the surface area of the filter paper‚ giving the solution more area to go through. A piece of wire is placed to avoid build-up of pressure‚ and easily pour the solution without spilling. 2.) Enumerate 2 techniques that can help

The 1960s was an era that changed America in so many ways. While many of the changes were in Civil Rights and in humanity in general‚ another change would come in the form of science and even the way we look at body armor and self protection in general. 1967 was the year in which a the world would have been introduced to Kevlar. Kevlar Not only influenced our military it also has changed the face of everyday American products. Discovered in 1965 an American chemist with the name of Stephanie Kwolek

spectroscopy which is defined as a combination of imaging and spectroscopy[2]. The modality of the imaging system will be a hyper cube with 2D spatial information and spectral information[14]. The materials in the scene are identified using spectral information. The location in the scene is identified using spatial information. In addition to image information‚ the classification and identification information is provided in Hyperspectral imaging systems[4]. It is useful for various industrial and

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

Goals The purpose of the lab experiment is to explore simple harmonic motion (SHM). We will accomplish this through the validation of harmonic calculations and ultimately creating a time piece (oscillator) Method In part A (Simple Pendulum) we will measure the effects of mass on the period of the pendulum. We will also calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small”
