A 50 g block of metal is heated to `200^(@)C` and then dropped into a beaker containing 0.5 kg of water initially at `20^(@)C.` if the final equilibrium temperature of the mixed system is `22.4^(@)C`, find the specific heat capacity of the metal. Given, specific heat capacity of water is 4182 J `kg^(-1).^(@)C^(-1)`.

Text Solution

Verified by Experts

`+Q_(hot)=-Q_(cold)`
`+(mCDeltaT)_("metal")=-(mCDeltaT)_(water)`
`+50xx10^(-3)xxCxx(22.4-200)=-0.5xx4182xx(22.4-20)` ltbr `impliesC=565.1" J "kg^(-1).^(@)C^(-1)`.
