It the temperature is increased from 0.5 to 0.8 of tm (k) what effect does this have on the recrystallization process? • for aluminum estimate the shear stress required to move a dislocation when r =20nm – use half the elastic modulus as the shear modulus. what is the effect of decreasing the radius of curvature of the dislocation?

At room temperature what happens to the average kinetic energy of the molecules of a solid, liquid, and a gas

Explain why pure hydrogen cyanide does not conduct electricity, but become a conductor when it is dissolved in water? (at room temp, pure hcn exists as a volatile liquid)

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
