Enthalpy of fusion of water
Could someone explain the concept of enthalpy of fusion of water and how to use it as illustrated in the homework question 5?
Re: Enthalpy of fusion of water
In this case, fusion is just heating the water to turn it from a solid to a liquid. To find the total enthalpy of fusion, you just multiply the enthalpy of fusion per gram by the total number of grams to find how many Joules you need for fusion. One you find the energy of a single photon, you can just divide to find the total number of photons.

Re: Enthalpy of fusion of water
The enthalpy of fusion of water is simple the amount of energy required to heat up one gram of water. Using it in context of the problem, you just multiply the grams of water by the given table value to find the total energy to heat up that amount of water. From there, you divide the total energy by the energy of each photon to find the total number of photons.
