How much heat should be given to an Alum...

How much heat should be given to an Aluminium sphere of 200 g to carry it from `26^(@)C` to `66^(@)C` temperature ? What will be the heat capacity of the Aluminium sphere ?
`C=0.215" cal g"^(-1)C^(0-1)`

Text Solution

Verified by Experts

`m=200g`
`T=T_(f)-T_(i)=67-27=40^(@)C`
`Q=?" "H_(C)=?`
`Q=mCDeltaT`
`=200xx0.215xx40`
`Q=1720` cal
Heat capacity of Aluminium sphere
`H_(C)=(Q)/(DeltaT)=(1720)/(40)`
`="43 cal "^(@)C^(@-1)`
