How much energy must be supplied to change 36 g of ice at `0^(@)C` to water at room temperature `25^(@)C`? `{:(,"Data for water",),(DeltaH_("fusion")^(@),,6.01kJ//mol),(C_(P" liquid"),,4.18JK^(-1)g^(-1)):}`

A

12 kJ

B

16 kJ

C

19 kJ

D

22 kJ

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaH=DeltaH_("Fusion")` of two moles `+msDeltaT`
`=6.01xx2+36xx4.18xx25xx10^(-3)`
`=16kJ`
