A physicist converted 2 kg of water at 37 degrees celcius to steam at 100 degrees celcius. Assuming no heat is lost, calculate the amount of energy needed to heat to 100 degrees celcius.

asked by i need help
  1. Yes, your wording indicates that you need help.

    You not only have to heat the water to 100 deg C
    You have to BOIL IT as well !
    so
    look up the specific heat of water, call it C
    then LOOK UP THE HEAT OF VAPORIZATION of water.

    then
    heat in = 2 * specifc heat * (100-37)
    +
    2 * heat of vaporization of 1 kg of water
