## Chemistry and Chemical Reactivity (9th Edition)

a) From the definition of heat capacity: $350\ g\times 4.184\ J/g.K\times (37-5)\ K=46.86\ kJ$ b) $46.86\ kJ\div 4.184\ kJ/Cal=11.2\ Cal$ Which is greater than the caloric content of the beverage. c) 240 Cal is much greater than the energy spent to heat the drink in the body.
