Final answer:

The question pertains to calorimetry, a chemistry topic, where heat transfer is measured using a coffee cup calorimeter. Core principles involved include specific heat and temperature change to compute the heat transfer when a hot iron piece is placed in water until thermal equilibrium is reached.

Step-by-step explanation:

Calorimetry Questions

The subject of the question is calorimetry, which is a section of chemistry that involves the measurement of heat transfer associated with chemical reactions or physical changes. A coffee cup calorimeter is often used in high school or college-level chemistry labs to determine the heat transfer associated with processes like dissolving,

mixing fluids, or chemical reactions. The student's question engages with concepts like heat capacity, specific heat, and temperature change, which are all fundamental to understanding calorimetry.

In the student's scenario involving a coffee cup calorimeter containing water and heated iron, the objective would be to calculate the final temperature when thermal equilibrium is reached using the formula q = mcΔT, where q is the heat transfer, m is the mass, c is the specific heat, and ΔT is the change in temperature.
