A researcher cools a 100 g100\ \text{g} tissue sample (assume c=3.5 J g−1 ∘C−1c = 3.5\ \text{J}\,\text{g}^{-1}\,^{\circ}\text{C}^{-1}) from 37∘C37^{\circ}\text{C} to 35∘C35^{\circ}\text{C} by placing it in contact with a cold plate. Using heat exchange reasoning, which statement is most consistent with the sign of qq for the tissue sample?
