Before going in for an annual physical, a 70.0-kgkgperson whose body temperature is 37.0∘C Consumes an entire 0.355-literliter can of a soft drink (which is mostly water) at 12.0∘C What will be the person's body temperature TfinalTfinal after equilibrium is attained? Ignore any heating by the person's metabolism. The specific heat capacity of a human body is 3480 J/kg⋅KJ/kg⋅K. Is the change in the person's body temperature great enough to be measured by a medical thermometer? (A high-quality medical thermometer can measure temperature changes as small as 0.1∘C∘C or less.)
