I have another question regarding thermodynamics,
A ship's anchor, made of 500kg of steel and initially at a temperature of 20 degree is dropped into the ocean which has a temperature of 7 degree. Determine the entropy change of the anchor.
Can i assume that since the ocean has a huge volume, the ocean water would not change temperature. Thus, the steel anchor will have a final temperature of 7 degree.
Solving it, using Cp= 4.002KJ/KG.K
The answer is 0.18162 KJ/K.
