Question Detail
Question
A sample of water at 40°C has a piece of metal at 150°C placed into it. Is this process spontaneous?
Correct Answer
Option B is the correct answer.
Detailed Explanation
This process is spontaneous as described. Heat always flows from higher temperature (150°C metal) to lower temperature (40°C water), raising the water's temperature and increasing the entropy of the universe due to energy dispersion.
Hint
The notes provide this reasoning.
