A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burner and placed on a kitchen counter. The temperature of the air in the kitchen is 76°F. If k = 0.34, the temperature of the liquid after 7 hours will be (blank) ºF. (Hint: Use Newton’s cooling model.)
