Problem 92P

You cool a 100.0-g slug of red-hot iron (temperature 745o C) by dropping it into an insulated cup of negligible mass containing 85.0 g of water at 20.0o C. Assuming no heat exchange with the surroundings, (a) what is the final temperature of the water and (b) what is the final mass of the iron and the remaining water?

Step-by-Step Solution:

Solution 92P Problem (a) To find the final temperature Step 1: Mass of iron M = 100g = 0.1 kg I Mass of iron M W = 85g = 0.085 kg Temperature of Iron T I = 745°C Temperature of Iron T = 20°C W Specific Heat c w = 4190 J/Kg.K c = 470 J/Kg.K I
