Bob orders a cup of hot coffee (0.22 kg) at a café. Finding the coffee to be too hot (56°C), he decides to put ice cubes with a total mass of 21 g into the cup. The ice is at an initial temperature of -5°C. Heat of fusion of water: 3.33 x 105 J/kg Specific heat of ice: 2090 J/(kg · K) Specific heat of water: 4190 J/(kg · K). a) What is the total energy needed to warm the...

As an eager scientist on a hot summer day you wish to determine how much ice to buy to add to your cooler which is filled with 32 cans of soda which are warm at 86.5°F. Each can has a mass of 375 g and ideally you want the temperature of the drinks to be 40.1°F. If there is no heat lost by the cooler and ignoring any heat lost to the soda containers, how much ice needs to be...
