States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

TO QUESTIONS 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? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases the speed of filtration. The crisscrossing of the folds help alleviate

Engineering Materials Week 2-Interactivity 3.1 What is the difference between crystal structure and crystal system? A crystal structure is described by both the geometry and atomic arrangements within cell‚ whereas a crystal system is described only in terms of the cell geometry. 3.2 For cubic crystals‚ as values of the planar indices h‚ k‚ and l increase‚ does the distance between adjacent and parallel planes (i.e.‚ the interplanar spacing) increase or decrease? Why? The interplanar spacing

The term ’powder’ really means that the crytalline domains are randomly oriented in the sample. Therefore when the 2-D diffraction pattern is recorded‚ it shows concentric rings of scattering peaks corresponding to the various d spacings in the crystal lattice. The positions and the intensities of the peaks are used for identifying the underlying structure (or phase) of the material. For example‚ the diffraction lines of graphite would be different from diamond even though they both are made of

Purpose: The purpose of our experiment was to determine the amount of water in copper sulfate pentahydrate expressed as a percent. Hypothesis: I think that bluestone crystals are 20% water‚ because it’s called pentahydrate (penta means five) and 1/5 of 100 (since it’s expressed as a percent) is 20‚ so I think bluestone crystals are 20% water. Procedure: The following list includes the materials and supplies we used in the experiment: 1) Crucible and Lid 2) Tongs 3) Alcohol Burner

made using the 40-pin AT89C52 microcontroller. This propeller display is mechanically scanned and displays the characters in digital format. Made from scrape it can be used anywhere and everywhere and the most amazing fact about the display is its crystal clear display. This display consists of just 23 bright LED’s which are rotated to show the display. For building the project‚ requirement 40 pin microcontroller and LED’s. this display can show the message‚ which will require a whopping 1504 LED’s

PIEZOELECTRICITY AND APPLICATIONS Piezoelectricity is the ability of some materials such as crystals and certain ceramics‚ to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are not short-circuited‚ the applied charge induces a voltage across the material. The word Piezo is derived from the Greek “Piezein”‚ which means to squeeze or press. The piezo material exhibits both “Direct piezo electric effect” as well as ‘Converse piezo electric

free to move past each other but still held together. Lastly there a solids which are molecules formed in a rigid formation which have a very strong attraction with repeating crystals and can only move in vibrations. Glass is none of the above‚ it is rigid like a solid‚ but its molecules are not arranged with repeating crystals which makes it amorphous like a liquid. "If you could preserve a window long enough‚ it might become a rigid puddle on the floor" (Ediger:1999‚Discover Magazine) Glass can
