Calculate the amount of heat required to con-vert 10 g of ice at `0^(@)C` to 10 g of water at `100^(@)C`
(Specific heat capacity of water =1 cal/g/`""^(@ )C`)

A

2000 cal

B

1800 cal

C

2200 cal

D

1600 cal

Text Solution

Verified by Experts

The correct Answer is:
B
The energy required to convert 10 g ice at `0^(@)c` to 10 g of water at `0^(@)` C to water at `100^(@)C=10xx100xx1=1000` cal
The energy required to convert 10 g water at `0^(@)` C to water at `100^(@)C=10xx100xx1= 1000` cal
Total energy required = 800 + 1000 =1800 cal
Hence, the correct option is (b).
