Lesson 7b: Insulation and Home Heating Fuels. 6 Sample Problem 2 Find m If an amount ice is heated from -20 to -10 degrees with 100 joules of heat energy, how much mass must be present?Examples: Ice Water Water Steam The reverse also applies that a substance cooled through a phase transition will release heat as requires less energy Although energy cannot be created or destroyed, it can be converted from one form to another (for example, internal energy stored in molecular bonds can beThus the mechanical energy balance is mainly used for purely-mechanical flow problems -i.e. problems in which heat transfer, chemical Heat as Energy Transfer Example Problem. Page 7.Solution to Specific Heat and Latent Heat Example Problem. Page 12. Problem Solving Tip.

For energy balances with reaction, we also have two methods for solving these types of problems: Heat of Reaction Method Heat of Formation Method.Example FR 9.5-1. The standard heat of reaction for the oxidation of ammonia is given below The next example looks at what happens to the heat energy that is not converted to electricity.The river flow rate is 100 m /s. Solution: This problem is very similar to example 2.8, in that we are adding a specified amount of heat to a flow of water, and need to determine the resulting temperature rise. Heat of vaporization is the amount of heat energy required to change the state of a substance from a liquid into a vapor or gas. It is also known as enthalpy of vaporization, with units typically given in Joules (J) or calories (cal).
