Problem

A hot iron skillet releases 650 J of energy to the surrounding countertop before reaching thermal equilibrium. Taking the skillet as the system and using the sign convention that QQ is positive when energy enters the system, what is the value of QQ for this process? (a) 0 J0\,\text{J} (b) −650 J-650\,\text{J} (c) +650 J+650\,\text{J} (d) −325 J-325\,\text{J}
