LARN 028 C7D4 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...

LARN 021 C6D1 Start the following in class: 1.  The required journal topics for today, J21, are: a. What is the difference between a physical change and a chemical change? b. Contrast the range of proportions of substances that can be incorporated into a mixture to the range of proportions of substances that can be incorporated into a compound. c. Contrast the change in the energy when a coarse mixture is produced to the expected change in the energy when substances react to form a compound. d.  Contrast how the properties of a coarse mixture differ from the properties of substances that make it up, and also contrast how the properties of the compound differ from the properties of the elements that reacted to produce it. e.  Contrast the ways a mixture might be separated into its components to the ways a compound might be separated. 2. Do all the pages in the chapter 2 Section Review packet as a formative assessment to find out some of the...

LARN 014 C4D2 Start the following in class: 1.  Do all the pages in the chapter 1 Section Review packet in one sitting as a formative assessment to find out some of the things that you do and do not know.  Do not interrupt your test taking to look up information in your text or on the internet.  After doing the section review packet, but before you demonstrate your understanding on our class' chapter test, you are to check all your responses in class by placing a green ink checkmark (√) to the left of the number for each individual correct response, and by lining out (striking trough) and inserting improved text in green ink when you judge that the suggested response is a better response.   While doing your checking, make sure that you clarify your understanding of each idea that you originally did not have a complete understanding of.  As a result of going through this process as requested, to prepare for...
