estion 3 of 12 incorrect ? Incorrect . Sapling Learning Mapo As an eager scientist on a hot summer day you wish to determine how much ice to buy to add to cooler which is filled with 32 cans of soda which are warm at 87.7 F. Each can has a mass of and g any heat lost to the soda containers, how much ice needs to be added to your cooler? (Assume ideally you want the temperature of the drinks to be 38.0°F. If there is no heat lost by the cooler an e temperature of the ice is 32.0 ) Number tiee lbs Tools x 10

Explanation / Answer

Given,

n = 32 ; Ti = 87.7 F = 30.94 deg C; Tf = 38 F = 3.33 deg C ; m = 387 g ; Ti = 32 deg F = 0 deg

we know that,

heat lost = heat gained

32 x 387 x 0.9 (30.94 - 3.33) = m x 80 x m x 1 x 3.33

m = 3693 g = 8.14 lb

Hence, m = 8.14 lb
