A well-insulated bucket of negligible heat capacity contains 134
g of ice at 0°C.
(a) If 21 g of steam at 100°C is injected into the bucket, what
is the final equilibrium temperature of the system?
°C
(b) What mass of ice remains?
g

question 1) answer clearly
In a calorimeter of negligible heat capacity, 200 g of steam at
150 ° C and 100 g of ice at -40 ° C are mixed. The pressure is
maintained at 1 atm. What is the final temperature and how much
steam, ice and water are present?
