Week 6:  11 October to 15 October 2021

11 October 2021:

No Class:  Columbus Day holiday.

12 October 2021:

In Class:  Heating and Cooling Curves (Chapter 1:8 to 1:10).  Energy Calculations (Chapter 1:5 to 1:6, 1:11 to 1:12):

  • q = m C ΔT
    q = m Hf
    q = m Hv
  • q = heatHf = heat of fusion
    m = massHv = heat of vaporization
    C = specific heat capacity
    ΔT = change in temperature
  • Expectations:  Students will be able to identify phases, phase changes, determine MP and BP, and calculate heat changes from heating and cooling curves.  Students will be able to calculate heat changes for phase changes and changes in temperature.

    Due:  The Characteristics of the Phases of Matter Worksheet.

    Homework:  Finish the Heating and Cooling Curves Worksheet.
    Here is the Heating and Cooling Curves Answer Key to help you.

    13 October 2021:

    No Class:  Chemistry does not meet on Wednesday.

    14 October 2021:

    Lab 5:
    Complete data collection and discuss Calculations for the The Atomic Mass of Pennium Lab.

    Expectations:  Students will be able to calculate weighted avereage atomic mass of elements from isotopic data.

    Lab Report:  Pending.

    Due:  The Heating and Cooling Curves Worksheet.

    Homework:  Finish the Heat Calculations Worksheet.  Here is the Heat Calculations Answer Key to help you.

    15 October 2021:

    In Class:  KMT of Gases and Boyle's Law.  (Chapter 1:27-28 to 1:21-22)

  •  P 1 V 1 =  P 2 V 2
  • P = pressure
    V = volume
  • Expectations:  Students will be able to solve Boyle's law gas problems.

    Homework:  Finish the Boyle's Law Worksheet and the Boyle's Law Answer Key.

    Note:  1st quarter ends 12 November 2021.
