According to the definition of International ohm, the resistance of a uniform column of mercury of length `106.3 cm` and of mass `14.4521 g`. When kept is melting ice, becomes `1 Omega`
(i) IF the temperature coefficient of resistance of mercury be `9 times 10^(-4^@)C^-1`. then what will be the resistance of that mercury column in boiling water?
(ii) IF the density of mercury be 13.59 g.`cm^-3` and its coefficient of volume expansion be `1.8 times 10^(-4^@)C^-1`. then what will be the resistivity of mercury at the temperature of boiling water.

Answer

(i) `1.09 Omega` (ii) `101 times 10^-6 Omega`cm
