A meal is 8000kJ. If all the energy is converted to heat, how much iced water with a temperature of 0 degrees must a person drink to maintain body temperature of 37 degrees?
How do I solve this - using the fact that 1mL water by 1 degree is 4.2Joules?
Heat gained by water = mass*4.2*(37-0)?

HELP!!

    yes.
    8,000,000 = mass H2O x specific heat x (Tfinal-Tinitial)
    Solve for mass H2O
