Question
Suppose that 0.95 g of steam (aka gaseous water), initially at 100 °C, condenses on a 75.0 g block of iron that is initially at 22 °C. What is the final temperature of the combined system when thermal equilibrium is reached?
Expert Solution
Step 1

we have to determine the equilibrium temperature for the system where 0.95 gra steam is condensing on a 75 g iron block.

 

 

 there are 3 disting stages

 conversion of 100 degree steam to 100 degree water [ condenstaion]

cooling of this water , so that there i an equilibrium reached .

 Latent heat of vaporization of water is  · 2.25×106 J  /kg

 

Specific heat of water = 4184 J/ kg K

Sp. heat of iron = 449 J/Kg K
