Final answer:

The question is about calculating the specific heat capacity of a piece of copper using the formula q=mcΔT and identifying the metal based on this value.

Step-by-step explanation:

The subject of the question relates to the specific heat capacity of metals and involves calculations based on the energy absorbed, mass, and temperature change. The student is essentially asking how to calculate the specific heat capacity of copper when it absorbs a certain amount of energy and undergoes a temperature change. This is a classic physics problem that applies the formula q = mcΔT, where q is the energy in joules, m is the mass in grams, c is the specific heat capacity in J/g°C, and ΔT is the change in temperature in °C. Using this formula, the specific heat of copper can be calculated given that the mass, energy absorbed, and temperature change are known. Comparing the experimental value with standard values, one can then confirm the identity of the metal as copper if the specific heat values are close. In this case, the student would compare the calculated specific heat with a known value for copper, which is approximately 0.39 J/g°C, based on other examples given.
