§4.4 - Learning Goals:

LG - Step 1: Read the learning goals above carefully. In the 3rd column mark the ones you feel good about with a “+” and the ones you might be a bit worried about with a “-”.

LG - Step 2: Take a good look at the categories of learning goals and compare them to your scores from S1. Now rank your categories from strongest to weakest using the letters A, B & C. (A - being strongest.)

LG - Step 3: Discuss what you have just filled in on your table with your neighbour(s). Try to explain / argue why you made that choice and ask the person for clarifying questions if need be.  

LG - Step 4: Think about what you have just discussed. Make any necessary changes in the marking of your table if need be. Use the last column please!

WB - Step 1: Take a look at the wordbank above, these are the new keywords for §4.4 Temperature & heat. Complete the wordbank by marking a “✓” if you agree with what is said and leave it empty if not. 

WB - Step 2: Discuss what you have just filled in on your table with your neighbour(s). Try to explain / argue why you made that choice and ask the person for clarifying questions if need be.  

WB - Step 3: Based on the steps you have just completed, take a look at the table below. What 3 things / goals are you going to focus on in this paragraph? Please write them down below.

Heat vs. Temp

• Heat - total amount of kinetic energy of the molecules in substance, measured in joules.

• Temperature - average amount of kinetic energy per molecule in a substance, measured in ºC or K.

P.182-183

Celcius vs Kelvin

• Celsius (ºC) - Based on freezing (0 ºC) and boiling (100 ºC) of water

• Kelvin (K) - Based on absolute zero (0 K), the lowest possible temperature, where particles stop moving.

P.182-183

Heat of combustion

Combustion reactions:

• exothermic, release a lot of heat  
• burning fuels produces heat that is used for many purposes.

Different fuels give off different amounts of heat, this is known as the heat of combustion.

P.182-183

Hw for lesson 5:

• Complete exercises 30-41 of §4.4 pages 184-187
• Read §4.5 pages 188-189
• Study the glossaries of §4.4 - §4.5 on Studygo.
