Homework Statement
A shipyard worker drops a hot steel rivet (mass 125g, temperature 350 degrees C)
into a river at temperature 5 degrees C, a distance 30m below. Stating any assumptions
you make, calculate the entropy change of the universe as a result of this event.
(specific heat capacity of steel ~0.4 J g-1 K-1).
Homework Equations
The Attempt at a Solution
If anybody could tell me if I'm on the right lines at all or what the heck to do with the fact that the rivet's being dropped from 30m I'd greatly appreciate it. Thanks!
