LARN 034 C9D2

LARN 034 C9D2 Start the following in class: 1.  The required journal focus question  J34 for today is: What evidence convinced Ernest Rutherford that most of an atom is empty space with each atom having an extremely small, dense, positively charged nucleus? 2. Doing ChemThink interactives are part of the core experiences for all chemistry students. Log onto the ChemThink web site http://simbucket.com/chemthinkserver/chemthink/  to do the tutorial and question set on Atomic Structure. Choose menu selections:  The Atom > Atomic Structure Tutorial.  [If you are logged onto the ChemThink web site, you do this by clicking on the green triangle in the white circle to the right of the displayed module's name. If you were taken directly to a web page with an orange Tutorial button and a blue Problem Set button, click on the orange Tutorial button.] If you do not have a copy of the worksheet that goes with this module, click on the provided link to the ChemThink worksheet for this module or, if that doesn't work,...

LARN 028 C7D4

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...
