Start the following in class:
1. Study the first page of the document entitled Temperature Scales, Conversions, SI Usages regarding temperature and then answer the following three questions as your journal focus questions for J28abcd.
- a. Reflect on how a liquid in glass thermometer responds to an increase in temperature. Why does a heated liquid expand up the narrow tube within a sealed thermometer?
- b. How does one convert a Celsius temperature to a kelvin temperature?
- c. What does kelvin temperature represent on the submicroscopic level?
- Recognize that the kelvin temperature scale’s zero point represents a situation in which molecules have no translational energy and represents absolutely the lowest conceivable temperature. The zero point of the kelvin temperature scale’s is called absolute zero. Know the relationship between the kelvin temperature scale used in the SI and the often used Celsius temperature scale and be able to convert temperatures from one scale to the other readily. [Hint: The numerical value on the kelvin temperature scale is always 273.15 more than the corresponding numerical value on the Celsius temperature scale.]
- d. What simple relationship allows one to readily convert a Celsius temperature scale reading to a kelvin temperature?
2. If you have not yet finished it in class, finish doing the Section Review packet for chapter 3 as a formative assessment to find out some of the things that you do and do not know, and not as a research project.
- If you did not obtain a section review packet for the chapter in class, go to MNSD Google Drive > Student Resources > Section Reviews and print off a section review for each individual section of the chapter.
- The section review packet for each chapter contains a separate section review document for each section of the chapter. So for example, a chapter with four sections would have four separate section review documents that need to be printed off. Each section review question document is identified by a name whose last two digits or last three digits represent the chapter number followed by the section number of that particular section.
- For each question or problem challenge, either answer the question to the best of your ability using one or more full sentences, or answer the problem to the best of your ability by recording any numbers and units together with the mathematical operations performed in symbolic terms, along with the solution to the problem which should be circled.
- This is an important assignment. Be sure to finish this packet in its entirety.
- After doing the section review packet, but before you demonstrate your understanding on our class’ chapter test, you will check all your responses using green ink check marks √ for each correct response, and by lining out (striking trough) and inserting improved text in green ink when you think the suggested response expresses your present understanding in a better way. Then, when you know what you didn’t understand, you will be able to study more efficiently by studying that which you corrected in green ink.
Recommended for those who have time left in their 45 minute study period, but not required of all:
1. Take Cornell notes on the differences between comparison ratios and rate ratios by referring to pages 5 and 6 of the document entitled Temperature Scales, Conversions, SI Usages . In this chapter we are focusing on using rate ratios to solve problems, but we will find much use of comparison ratios in a later chapter of the book to solve problems dealing with gases.
2. Check out the student made Quizlet for chapter 3 at https://quizlet.com/160587029/honors-chem-chapter-3-flash-cards/ . Do all the definitions reflect a thorough and correct understanding?
