(a) A person drinks fours glasses of cold water (3 °C) every day. The volume of each glass is 250 mL. How much heat (in kJ) does the body have to supply to raise the temperature of the water to 37 °C, the body temperature? (b) How much heat would your body lose if you were to ingest 800 g of snow at 0 °C to quench thirst? (The amount of heat necessary to melt snow is 6.01 kJ/mol). Density of water: 1 g/mL Specific heat of water: 4.184 J/g. °C H2O= 18.02 g/mol
