specific heat of water from -15 to 0 C + heat of melting + specific heat of water from 0 C to 100 C + heat of evaporation + specific heat of water from 100 C to 125 C
OpenStudy (sweetburger):
the formula to find how much energy is required to raise temperatue is Q= MspDeltaT Q stands for energy, M stands for mass not molarity, Sp stands for specific heat of the substance which for water 4.18kj i think cant be sure, and Delta T is the desire temperature - the starting temperature. hope this helps sorry for the late reply
