Vedclass · Accepted Answer

$(i) T, (ii) F, (iii) T$

Vedclass · Answer

(B) $(i)$ For electrolytic solutions,conductivity increases with an increase in temperature because the kinetic energy of ions increases and viscosity of the solvent decreases,leading to higher ionic mobility. Thus,statement $(i)$ is $T$.$(ii)$ $Cu$ is a metallic conductor. For metallic conductors,conductivity is inversely proportional to temperature due to increased scattering of electrons by vibrating metal ions. Thus,statement $(ii)$ is $F$.$(iii)$ As temperature increases,the resistance of metallic conductors like $Cu$ increases,which means conductivity decreases. Thus,statement $(iii)$ is $T$.Therefore,the correct sequence is $(i) T, (ii) F, (iii) T$.

Identify True $(T)$ or False $(F)$ for the following statements :
$(i)$ As temperature of solution is more,then conductivity is more.
$(ii)$ Conductivity of $Cu \propto$ temperature.
$(iii)$ As temperature increases,conductivity of $Cu$ decreases.
