Question

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?

a) Calculate the final temperature and the amounts of steam, ice, and water.
b) The final temperature cannot be determined.
c) The pressure is irrelevant to the final state.
d) The system reaches thermal equilibrium with the surroundings.

Answer 1

To determine the final temperature and amounts of steam, ice, and water in a calorimeter, the principles of heat transfer and energy conservation can be used.

Step-by-step explanation:

The final temperature and the amounts of steam, ice, and water can be determined using the principles of heat transfer and energy conservation.

To solve this problem, we can use the equation:

qice + qsteam + qwater = 0

where qice, qsteam, and qwater represent the amounts of heat transferred to the ice, steam, and water respectively.

Using the specific heat capacities and heat of fusion of water and steam, we can calculate the final temperature and the amounts of steam, ice, and water present.
