Quick Recall
Let's quickly refresh what you already know. These short recall activities will help you bring the most important ideas back to mind before reviewing them.
QUICK RECALL
Recall Activity
Complete the three statements from memory before revealing the answer.
A. Add 273.15. B. Multiply Celsius by 9/5 and add 32. C. Equal temperature and no net heat transfer. D. Absolute temperature scale.
Reveal Answers
A: Celsius to kelvin. B: Celsius to Fahrenheit. C: thermal equilibrium. D: kelvin.
Why it works: The equations distinguish offsets, scale factors, and the physical equilibrium condition.

Great! Now let's review the most important ideas you'll want to remember.
Essential Idea
Take one last look at the most important concept from this unit. If you remember this idea, the rest will come back much more easily.
ESSENTIAL IDEA
Temperature Scales and Equilibrium
Temperature scales are related by linear conversions. Use kelvin for absolute temperature and Celsius or Fahrenheit when the problem calls for those scales. Thermal equilibrium is reached when interacting systems have equal temperatures, regardless of which valid scale reports them.
T(K) = T(°C) + 273.15; T(°F) = (9/5)T(°C) + 32
Example: 20 °C = 293.15 K = 68 °F.
Sensei note: Convert the temperature value, but a change of 1 °C equals a change of 1 K.

Confidence Check
You've refreshed the essential ideas. Now answer this quick confidence check to confirm you're ready to move on.
CONFIDENCE CHECK
Convert and Interpret
Answer all three without notes.
Object A is at 68 °F and object B is at 10 °C. Convert A to Celsius and predict the initial heat-transfer direction.
Reveal Answers
68 °F = 20 °C. Heat transfers from A at 20 °C to B at 10 °C.
Why it works: Comparing values on the same scale makes the higher-temperature direction clear.
