Calculate the number of `KJ` necessary to raise the temperature of `60.0 g` of aluminium from `35^(@)` to `55^(@)C`. Molar heat capcacity of `Al` is `24 J mol^(-1)K^(-1)`

Text Solution

Verified by Experts

`q = n xx C xx DeltaT = ((60)/( 27) mol) ( 24 J mol^(-1) K^(-1)) ( 55 - 35K) =1066 .7 J =1.07 kJ `
