What will be the final temperature of a 10.0 g piece of iron (C_P =25.09 J/(mol · ) initially at 25 $\circ$ C, if it is supplied with 9.5 J from a stove?

Question

Quizplus · Accepted Answer

We can use the formula q = mCΔT to find the temperature change of the iron, where q is the heat supplied, m is the mass of the iron, C is the specific heat of iron, and ΔT is the change in temperature.

Plugging in the given values, we get:
9.5 J = (10.0 g)(25.09 J/(mol · °C))(ΔT)
Solving for ΔT, we get:
ΔT = 0.038°C

Therefore, the final temperature of the iron is:
25°C + 0.038°C = 25.038°C

Rounding to the nearest tenth, we get:
25.0°C + 0.0°C = 25.0°C

Choice B is the only one that matches our calculated answer, so the best choice is B.
