Answer:
Explanation:
Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):
Now, by stating the heat capacity definition:
Solving for the equilibrium temperature:
Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.
Best regards.
