This lesson
Some practical info
Understanding a calorimeter
Exercises specific heat capacity
Double glass
Heat transfer
Quality of insulation
Slide 1 - Diapositive
Learning goals
At the end of this lesson you can:
Explain how a caloriemeter works and what it is used for
Rearrange the formula for specific heat
Explain how double glass works
Name the three forms of heat transfer and examples for each
Do calculations on quality of insulation
Slide 2 - Diapositive
Practical info
The practical will take place the first week after the carnavals break.
For this you will have to study chapter 3 section 1 to 4.
If we have time left this period, we will also do a poster assignment.
If we don't have enough time, we will do the poster assignment next period.

Slide 4 - Diapositive
Understanding
a calorimeter
What components do you notice?
What is their function?
What is the purpose of a calorie meter?
Slide 5 - Diapositive
Understanding
a calorimeter
A calorimeter is used to measure the amount of heat required to raise the temperature of a certain amount of water
Slide 6 - Diapositive
Specific heat capacity
Q: Heat in joules (J)
c: The specific heat capacity of a s substance (J/(g•ºC)
m: The mass of a substance in grams (g)
ΔT = T
