Part A State the law of conservation of energy The law of conservation of energy states that energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms. The law of conservation of energy states that energy can not be created but it can be destroyed. Energy can be transferred from one object to another can be destroyed in a chemical reaction, and it can assumo different forms The...

Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m⋅Cs⋅ΔT where Cs is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change q=n⋅ΔH where, n is the number of moles and ΔH is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy...
