Calculate heat required to convert 3 kg of water at 0^(@)C to steam at 100^(@)C. Given specific heat capacity of H_(2)O = 4186 "J kg"^(–1)k^(–1) and latent heat of steam = 2.256 xx 10^(6) J/kg.

Answer»

Solution :HEAT REQUIRED to CONVERT `H_(2)O` at `100^(@)` to steam at`100^(@)` C is = ML
`=3xx2.256 xx10^(6)`
=6768000 j
Total heat = 8023800 J
