the steel has stronger force between its atoms compared to chalk
Conduction is useful because it allows you to heat solids. FACT: Solids heat faster than liquids and gases.
it must combine magnification and resolution
All solids expand as they are heated but I guess you want some examples where this is either useful or a problem: Useful * Bimetalic strips used in thermostats. They are made by joining 2 metals with different rates of expansion together, as they get warm they bend one way, as they get cold they bend the other. Problem * Long pipes have to have S bends in them to allow for the expansion/contraction otherwise they buckle or snap. * Railway lines are laid with gaps in them so that there is room for them to expand. (This is where the ta ta ta tap sound comes from as the wheels go over the gaps.) * Bridges have to have be suspended to allow for expansion.
Quartz is a natural substance, SiO2, and has a number of properties useful to us. It has a high melting point compared to ordinary glass, it has some very useful piezoelectric properties, It has a high propensity to crystallize when in compound with other substances. Hence many of our precious jewels.
Entropy always increases :(. One way of looking at it is all energy wants to be waste heat, and all life and machinery is a system of toll bridges, extracting useful work from the energy on the way to it's final destination. Once the energy arives, it has no desire to go anywhere so toll bridges don't turn a profit.
because it is?gjkl#
many have been used, but reinforced concrete is preferred now as properties are more predictable and consistent.
Most modern bridges are steel structure or framework. Limestone, dolomite and marble have been used in many historic buildings attesting to their durability.
Granite is one kind of hard rock.
Because It Is A Strong Alloy ThereFore It Is The Best In Its Group To Do The Job.
"Mentals"? I think you mean "Metals". There are several useful properties in metals. Its hardness and density are useful in building and constructing. Its smooth nonporous surface is useful in many different ways, its flexibility and endurance are great for making earth quake proof buildings and bridges.Look at the San Francisco bridge. Exponentially, there are no limit to the useful properties of metal. All you have to do is look it up.

Nope, bases actually gives soaps their useful properties.
IcosahedronDodecahedronTetrahedronCubeOctahedronHope these are useful
formula for determining the useful life of a building?
because if they don't stand they will not be useful
Cranes that are used for building bridges or other large structures are used because they can carry very large weights across very long spans and heights.
