NYSTCE Chemistry: Thermodynamics - Chapter Summary
This chapter is filled with fun and engaging video lessons designed to improve your ability to answer thermodynamics questions on the NYSTCE Chemistry assessment. Reviewing the lessons can help you:
- Describe heat changes, phase changes, heating curves and energy diagrams
- Share details about the endothermic and exothermic reactions
- Define and examine the equation for thermal expansion
- Provide the meaning of the zeroth law of thermodynamics
- Discuss laws of thermodynamics
- Explain the Carnot cycle
You can use the resources in this chapter as a study guide for the assessment. Watch the lessons to gain insight into the concepts you will be expected to address on the exam. Take the self-assessment quiz with each lesson to practice answering questions similar in format and content to those on the test.
NYSTCE Chemistry: Thermodynamics Chapter Objectives
The New York State Teacher Certification Examinations (NYSTCE) Chemistry assessment makes sure educators are prepared to obtain the certification needed to teach chemistry in state classrooms. The test is broken into seven subareas and consists of 90 selected-response items and 1 constructed-response item. It lasts four hours, with 15 additional minutes dedicated to a computer-based test (CBT) tutorial and nondisclosure agreement. To pass, you must earn a minimum score of 220.
Lessons in this chapter cover topics found in the energy, chemical bonds and molecular structure subarea, which constitutes about 16% of the total test. All questions in this part of the test are multiple-choice. Review the lessons to enhance your knowledge of thermodynamics as you study for the test. You can use timelines with video tags to visit key topics within the video lessons without watching them in their entirety. Any questions you have about lesson topics can be submitted to experts who are eager to help.
1. Phase Changes and Heating Curves
Learn the phases - gas, liquid, solid and plasma. Learn what a phase diagram is and what terms describe the movement between phases: melting, sublimating, freezing, vaporization, condensation, and deposition. Discover why heating curves have plateaus, what a phase transition is, and what happens during this transition.
2. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
3. Thermal Expansion: Definition, Equation & Examples
In this lesson, you will learn what thermal expansion is and discover an equation for calculating how much different materials expand. You'll look at a number of examples of thermal expansion. A short quiz will follow.
4. The Zeroth Law of Thermodynamics
After watching this video, you will be able to state the zeroth law of thermodynamics, what it means, and why it is important. A short quiz will follow.
5. The Laws of Thermodynamics
Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.
6. Efficiency & the Carnot Cycle: Equations & Examples
After watching this video, you will be able to explain the Carnot Cycle, including what it represents and how it works, and calculate the efficiency of a particular Carnot engine. A short quiz will follow.
