What is the final temperature of the water and iron at thermal equilibrium assuming that qwater = -qiron ?

Question

A 20 g piece of iron with T = 300 °C is placed in 250 mL of water in a glass beaker with T = 30 °C. What is the final temperature of the water and iron at thermal equilibrium assuming that qwater = -qiron ? The specific heat capacity of iron is 0.451 J g-1 °C-1.
A: 270°C
B: 330°C
C: 32.31°C
D: 27.65°C
E: 165°C

Answer 1

C. You wouldn't expect the final temperature to be above the water boiling point or less than the water's initial temp.
