Answer
The temperature of the ice chest increases.
Work Step by Step
According to the laws of thermodynamics, heat flows from an object with a higher temperature to an object with a lower temperature until they both acquire the same temperature. Since the ice has a higher temperature (0∘C) than the ice chest (-8∘C) the heat flows from the ice to the ice chest until they both acquire the same temperature. The ice chest absorbs the heat and thus, the temperature of the ice chest increases.
