Passage / Comprehension
A hypothetical material has melting point 0°C, boiling point 100°C, liquid specific heat 1 cal g⁻¹ °C⁻¹, fusion latent heat 100 cal/g and vaporization latent heat 500 cal/g. Saturated vapour at 100°C is mixed with solid at 0°C at the same pressure in an insulated negligible-capacity vessel.
What ice-to-steam mass ratio gives final liquid water at exactly 100°C with no steam left?
Options:
Answer:
B
Solution:
Each gram of steam releases 500 cal. Each gram of ice needs to become water at .
