Why the conductivity of H3BO3 is lower than H3PO4 while they each free the same amount of ions per mole?

Because H3BO3 is a weak acid, where H3PO4 is a strong acid. Strong acids dissociate 100%, whereas weak acids do not.

Lower salinity increases the conductivity of sea water?
yes it does
What large materials are good thermal conductors and good electrical conductors?
from wiedemann franz law we know that thermal conductivity/electrical conductivity=constant that is sigma inv. proportional to k thus a material having large electrical conductivity has low thermal conductivity and moreover we know R=pL/A p=RA/L 1/P=L/RA i.e lower area means greater conductivity(electrical) and lower thermal conductivity
Distillation produces water that is?
purer and with lower conductivity due to reduced ionic content
What materials are partially conductive?
conductivity is a result of free electrons meaning that they can be riped away fast and the temperature of the material. a colder material has a lower resistance and higher conductivity. materials like metallic oxides have low conductivity and materials like pure copper and aluminum have high conductivity.
Is ductile iron generally conductive?
Ductile iron is generally conductive with a thermal conductivity of 36 watts per meter. Compared to grey iron, its conductivity is lower.
How do i confirm that this water is demineralized water?
The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has a conductivity of around 5 S/m (Siemens per metre) Drinking water has a conductivity of 0.005 - 0.05 S/m . Ultra-pure water has a much lower conductivity of 5.5 x 10-6 S/m - a million times smaller than that of sea water.
