The Solid State General characteristics of solid state: Definite mass‚ volume and shape Short intermolecular distances Strong intermolecular forces Fixed lattice positions of the constituent particles Incompressibility and rigidity Classification of the solid state: Crystalline Amorphous (sometimes called pseudo solids or super-cooled liquids) Differences between the crystalline and amorphous solids Crystalline Have definite characteristic geometrical shape Melt at a sharp and characteristic temperature

American history and society. From the time the first settlers arrived in the New World from Europe‚ families and communities have relied on farms both big and small. Up until the 1930’s‚ there were few changes in the agriculture industry‚ but following the Great Depression and World War II‚ there was an explosion in farming technology‚ productivity‚ and the amount of federal government intervention. These changes led to a revolution in agriculture from about 1950 to 1970 that shaped the industry

comprises liquid waste discharged by domestic residences‚ commercial properties‚ industry‚ and/or agriculture and can encompass a wide range of potential contaminants and concentrations. In the most common usage‚ it refers to the municipal wastewater that contains a broad spectrum of contaminants resulting from the mixing of wastewaters from different sources. Sewage is correctly the subset of wastewater that is contaminated with feces or urine‚ but is often used to mean any waste water. "Sewage"

Reducing noise pollution. Noise pollution occurs when noise reaches levels harmful to health and the public peace. The noise is an undesirable‚ or to man unpleasant sound. The intensity of sound is expressed in units of sound pressure‚ or decibels. A very low whisper is about 10 dB‚ while a conversation in a normal tone is about 60 db and the sound of a rock concert reaches about 100 db. The main sources of noise are: means of transport such as cars‚ buses and motorcycles; industrial activities;

Industrial waste is a type of waste produced by industrial activity‚ such as that of factories‚ mills and mines. It has existed since the outset of the industrial revolution.[1] Much industrial waste is neither hazardous nor toxic‚ such as waste fiber produced by agriculture and logging.[2] Toxic waste‚ chemical waste‚ Industrial solid waste and Municipal solid waste are designations of industrial waste. Sewage treatment can be used to clean water tainted with industrial waste. Penalties and fees

Habitat loss—due to destruction‚ fragmentation or degradation of habitat—is the primary threat to the survival of wildlife in the United States. When an ecosystem has been dramatically changed by human activities—such as agriculture‚ oil and gas exploration‚ commercial development or water diversion—it may no longer be able to provide the food‚ water‚ cover‚ and places to raise young. Every day there are fewer places left that wildlife can call home. There are three major kinds of habitat

Nowadays almost all schools include such subjects as art‚ drama‚ and music in their educational program. Therefore‚ by the time when children graduate school they have general understanding and basic knowledge in all of them. In my opinion‚ it is a positive tendency and these subjects should indeed be a part of every child’s education. I would like to introduce several reasons and examples that I believe will support my viewpoint. First and foremost‚ teaching of subjects such as art‚ drama and music
