Final Answer:

The change in temperature of the copper is 484.225 °C.

Step-by-step explanation:

To calculate the change in temperature, we can use the formula Q = mcΔT, where Q is the amount of energy transferred by heat, m is the mass of the copper, c is the specific heat of copper, and ΔT is the change in temperature.

Rearranging the formula to solve for ΔT, we get ΔT = Q / (mc). Plugging in the given values, we have ΔT = 66200 J / (0.190 kg * 385 J/kg • K) = 484.225 °C.

The specific heat of a substance is a measure of how much heat energy is required to raise the temperature of a given mass of that substance by a certain temperature. In this case, the specific heat of copper is 385 J/kg • K, which means it takes 385 joules of energy to raise the temperature of 1 kilogram of copper by 1 degree Kelvin.

Given that the amount of energy transferred by heat to the copper is 66200 J and the mass of the copper is 0.190 kg, we can calculate the change in temperature using the formula ΔT = Q / (mc), resulting in a change in temperature of 484.225 °C.

In summary, when a 0.190 kg piece of copper receives 66200 J of heat energy and has a specific heat of 385 J/kg • K, the change in temperature experienced by the copper is calculated to be 484.225 °C.
