Answer» Correct Answer - 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). |
