What is the heat required in kilocalories to convert 2 kg of ice at 0°C completely into steam at 100°C?

Question

ddcamp · Answer

1 calorie will raise 1 gram of water by 1°C
1kg is 1000g
You're raising the temperature by 100°C

@DDCamp just doing the temperature change doesn't account for the substantial energy required for the two phase changes.  Just converting from ice to water is almost as much energy as heating the water from 0 to 100 C, and converting to steam is much more.

@bradely I'm not so sure about your result — at least one of us appears to be mistaken about the latent heat of vaporization of water.  Also, the specific heat of water...
