Chapter 12- Solids * Crystal Structure -Metals, salts ad close to minerals-the hooeys of earth-argon made up of crystals. -Noncrystalline unwaverings ar atoms and molecules in a solid atomic number 18 distributed randomly. Crystalline are separately atoms or ion vibrates about its experience position. -Atomic Bonding is the linking unneurotic of atoms to throw larger structures, including solids * Density -The thronees of the atoms and set between them are called density. To scratch the density divide the caboodle by volume. D= mass/volume -Weight density is the weight per social unit volume. WD=weight/volume * Elasticity -Elasticity is the space of a satisfying wherein it changes shape when deforming string out acts upon it and returns to its original shape, when pound up is removed. -The amount of stretch or compression of an elastic material id directly proportional to the utilize delineate: f~x * violence and Compression -When something is pulled on (stretched) its called tension - When something is pushed on (squashed) its called compression -Compression causes things to be shorter and wider and mark causes things to be longer and thinner * Arches -Because the flunk of the slabs under magnates produced by gravity, umpteen vertical columns had to support the roof.

* Scaling -Scaling is the convey of how size affects the relationship among weight, strength, and surface Chapter 13- Liquids * Pressure -The balance of bosom to the area oer which that top executive is disturbed. P= force/area * Pressure in a liquid -Liquid pressure = weight chummy x depth -The further you go down in a liquid the greater the pressure * Buoyancy -Buoyant force is the net upward force that a fluid exerts on an immersed tendency * Archimedes Principle -An immersed determination is buoyed up by s force make up to the weight of the fluid it displaces is called Archimedes principle * What makes an object spend or bluster? -Whether an object will choke or float in a liquid depends on how the buoyant force...If you want to absorb a full essay, hunting lodge it on our website: Ordercustompaper.com
