A hyperthermic (feverish) male, with a body mass of 104 kg, has a mean body temperature of 107F. He is to

be cooled to 98.6F by placing him in a water bath, which is initially at 77F. Calculate what is the minimum

volume of water required to achieve this result. The specific heat capacity of a human body is 3.5 kJ/(kg·K). The

specific heat capacity for water is 4186 J/(kg·K). You must first find an appropriate formula, before substituting

the applicable numbers.
