Passage / Comprehension
A closed frictionless piston maintains one atmosphere. Initially it contains 20 g ice at 0°C. Then 10 g saturated steam at 100°C enters and is retained. Use cal/g, cal/g and cal g⁻¹ °C⁻¹.
What is the final equilibrium state at one atmosphere? Neglect losses and vessel heat capacity.
Options:
Answer:
C
Solution:
Ice needs to become water at 100°C. Condensation needed is , less than 10 g supplied. Final temperature is 100°C, with about 3.333 g steam remaining.
