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.
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 !
look up the specific heat of water, call it C
then LOOK UP THE HEAT OF VAPORIZATION of water.
heat in = 2 * specifc heat * (100-37)
2 * heat of vaporization of 1 kg of water
