This homework page is included in the lesson: Phase Changes, Phase Diagrams, & Heating/Cooling Curves. These homework pages can be used for homework or class practice.
Two versions of this homework:
Honors version: (2 pages) Honors students will answer more complex questions, and calculate heat of fusion and heat of vaporization.
Standard version: (1 page) The standard version does not include heat of fusion or heat of vaporization problems. The questions are a less complex.
A complete KEY is included.
Objectives:
- Discuss the role of vapor pressure in changes of state between a liquid and its gas.
- Explain forces of attraction and energy changes involved in change of state.
- Describe the relationship between energy and change of state in terms of endothermic or exothermic processes.
- Identify the six changes of state, and the energy involvement associated with each change.
- Calculate the amount of energy absorbed or released in order for a change of state to occur. (Hvap, Hfus)
Prior Knowledge:
- Understand the concepts of phases of matter and how they relate to energy
- A good understanding of phase changes related to energy changes, changes in attractive forces, and particle movement and arrangement
This homework is appropriate for grades 9-12 chemistry, or physical science.
