To make a potato salad, a chef cooked some unpeeled potatoes in boiling water at 100C. Once the potatoes have been cooked through and drained, he sets them aside, uncovered, in a room at 28C. Two minutes later, he picks up a potato to start peeling, but to his horror, the potato is still 85C - much too hot to work with. He knows that the potato must at least be within 10C of his body temperature (37 C) before he could start peeling them safely. At least how many minutes should the chef let the potato cool before he can start to peel? O 9.2 minutes 0 11.4 minutes 0 17.8 minutes 0 14.6 minutes
