Week 7:  19 October to 23 October 2020

19 October 2020:

No Class:  Teacher PD day.

20 October 2020:

In Class:  Heat versus Temperature and the Phases of Matter (Chapter 1:4).

Expectations:  Students will be able to predict the direction of heat flow (given temperature), calculate temperature changes, and convert °C to K units.

In Class:  Heating and Cooling Curves (Chapter 1:8 to 1:10).

Expectations:  Students will be able to identify phases, phase changes, determine MP and BP, and calculate heat changes from heating and cooling curves.

Due:  The Introduction to Heat Worksheet.

Homework:  Finish the Characteristics of the Phases of Matter Worksheet.
Here is the Characteristics of the Phases of Matter Answer Key.

21 October 2020:

In Class:  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 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.

    22 or 23 October 2020:

    Lab 4:
    Complete data collection and discuss Calculations for the Heat of Fusion Lab.

    Due:  The Heating and Cooling Curves Worksheet.

    Homework:  Finish the Heat Calculations Worksheet and the Heat Calculations Answer Key.

    Note:  1st quarter ends 12 November 2021.
