(challenge) 3 kg of ice are placed in a 35cm x 35cm x 25cm (outside dimensions) Styrofoam TM cooler with 3cm thick sides. Approximately how long will its contents remain at 0 C if the outside is a sweltering 35.C? You can ignore effects of condensation, convection, and conduction of the air inside, and assume all six sides of the cooler are exchanging heat with environment equally. Hint: you'll need to use the equation from Activity 5.14 B) and find the relevant equation for heat (from 7A) for the described interval
