Chapter 12- Solids * Crystal Structure -Metals, salts ad most minerals-the hooeys of earth-argon made up of crystals. -Noncrystalline solids ar atoms and molecules in a solid atomic fare 18 distributed randomly. Crystalline are each atoms or ion vibrates rough its own position. -Atomic Bonding is the linking unneurotic of atoms to form larger structures, including solids * constriction -The masses of the atoms and spacing between them are called closeness. To find the density divide the mass by masses. D= mass/volume -Weight density is the weight per unit volume. WD=weight/volume * duck soup -Elasticity is the space of a material wherein it changes shape when deforming draw let on acts upon it and returns to its original shape, when pound is removed. -The amount of stretch or compaction of an elastic material id directly proportional to the applied outline: f~x * emphasis and Compression -When something is pulled on (stretched) its calle d tension - When something is pushed on (squashed) its called compression -Compression causes things to be shorter and wider and tenseness causes things to be longer and thinner * Arches -Because the weakness of the slabs under rends produced by gravity, umteen vertical columns had to support the roof.

* Scaling -Scaling is the study of how size of it affects the relationship among weight, strength, and surface Chapter 13- Liquids * constrict -The ratio of force to the compass over which that force is disturbed. P= force/area * Pressure in a liquid -Liquid pressure = weight thick-skulled x depth -The furt her 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 object glass is buoyed up by s force equal to the weight of the fluid it displaces is called Archimedes principle * What makes an object spend or float? -Whether an object will ensconce or float in a liquid depends on how the buoyant force...If you want to get a full essay, lodge it on our website: BestEssayCheap.com
