A piece of metal weight 45 g is air and 25 g in a liquid of density `1.5 xx 10^(3)kg-m^(-3)` Kept at `30^(@)`. When the temperature of the liquid is raised to `40^(@)C`, the metal piece weight 27g. The density of liquid at `40^(@)C` is `1.25 xx 10^(3) kg-m^(-3)`. The coefficient of linear expansion of metal is

A piece of metal weighs 46 g in air and 30 g in liquid of density 1.24 xx 10^3 kg m^(-3) kept at 27^0C . When the temperature of the liquid is raised to 42^0C , the metal piece weights 30.5 g . The density of the liquid at 42^0 C is 1.20 xx 10^3 kg m^(-3) . Calculate the coefficient of linear expansion of the metal.

A piece of metal weighs 46 g in air and 30 g in lipuid of density 1.24 xx 10^3 kg m^(-3) kept at 27^0C . When the temperature of the liquid is raised to 42^0C the metal piece weights 30.5 g . The density of the liqued at 42^0 C is 1.20 xx 10^3 kg m^(-3) . Calculate the coefficient of linear expandsion of the metal.

The density of a liquid at 100^(@)C is 8.0g//cm^(3) and at 0^(@)C is 8.4g//cm^(3) , the coefficient of cubical expansion of the liquid is
