WebTherefore, the heat energy needed for step 1 is 11.4624 kJ. (D) For step 2, we need to calculate the heat energy required to vaporize 55.0 g of liquid water at 100.0 °C. The formula for calculating heat energy during a phase change is: Q = m × AHvap where Q is the heat energy, m is the mass, and AHvap is the enthalpy of vaporization. WebEnergy is a conserved quantity. the law of conservation of energy states that energy can be converted in form, but not created or destroyed. Examples of energy include light energy, heat energy, mechanical energy, electrical energy, sound energy and many more. The unit of energy is the joule.
