Choose the correct alternative: Alloys of metals usually have `(greater//less)` resistivity than that of their constituent metals.

Choose the correct alternative: Alloys usually have much (lower//higher) temperature coefficients of resistance than pure metals.

Choose the correct option- Bronze alloy is used in-

Choose the correct alternative: Aniline is less/more basic than ethylamine.

Choose the correct option-Bronze alloy is made up of-

If the resistivity of an alloy is rho' and that of constituent metals is rho , then

Choose the correct alternative: The resistivity of a typical insulator (e.g., amber) is greater than that of a metal by a factor of the order of (10^22//10^3) .

Choose the correct option- Bronze is an alloy because it is-

Choose the correct alternative: Heavy metal associated with bone deformation is Cadmium/Mercury.

Choose the correct alternative from the clues given at the end of the each statement: The size of the atom in Thomson model is..... the atomic size in Rutherford model( much greater than /no different from/ much less than.)
