    The refrigerated one will be smaller. The heated one will be larger. Air (any gas) occupies a smaller volume when it is cooled and a larger volume when it is heated.

    The balloon that is larger was in the slightly warm oven getting heated. The balloon that is smaller was in the refrigerator. When air is in cold temperatures it contracts and when air is in warm temperatures it expands.
