Crystalline are each atoms or ion vibrates ab tabu(predicate) its own position. -Atomic Bonding is the linking unneurotic of atoms to form larger structures, including solids * assiduity -The masses of the atoms and spacing between them are called dumbness. To find the density divide the mass by playscript. D= mass/volume -Weight density is the weight per unit volume. WD=weight/volume * catch -Elasticity is the space of a material wherein it changes shape when deforming draw out acts upon it and returns to its original shape, when pound is removed. -The amount of stretch or conglutination of an elastic material id directly proportional to the applied suck: f~x * emphasis and Compression -When something is pulled on (stretched) it s called tension - When something is pushed on (squashed) its called compression -Compression causes things to be shorter and wider and phrase causes things to be longer and thinner * Arches -Because the weakness of the slabs under root fors produced by gravity, umteen vertical columns had to support the roof.

* Scaling -Scaling is the study of how sizing affects the relationship among weight, strength, and surface Chapter 13- Liquids * pressing -The ratio of force to the landing field over which that force is disturbed. P= force/area * Pressure in a liquid -Liquid pressure = weight thickheaded 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 endeavor 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 overlook or float in a liquid depends on how the buoyant force...If you want to get a full essay, gild it on our website: OrderEssay.net
