urgent engineering question! please help!?
for each of the following pairs of materials, decide which has the larger thermal conductivity. JUSTIFY the choices.
1.pure copper; aluminum bronze (95wt% Cu-5wt%Au)
2.fused silica, quartz
3.linear polyethylene, branched polyethylene
4.random poly(styrene-butadiene )copolymer, alternating poly(styrene-butadiene )copolymer
thank you so so so much!
Au is gold which is almost as good a thermal conductor as copper, so likely about as good as the aluminum bronze by wt and volume, but not as good as pure copper. Neil
