📚 Quick Recap

Temperature measures how hot or cold something is by quantifying the average kinetic energy of its particles — a concept so fundamental it needed its own dedicated scales and instruments.

🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4

1Convert 50°C to Kelvin.

2Convert 300 K to Celsius.

3Convert 20°C to Fahrenheit.

4Convert 104°F to Celsius.

🧮 Section B · Problem Solving ● INTERMEDIATE 4 × 3 = 12

5What does a higher temperature indicate about a substance's particles?

6Why can absolute zero never actually be reached in practice?

7Convert -10°C to Fahrenheit.

8Convert 212°F to Kelvin (find Celsius first).

🚀 Section C · Challenge ● CHALLENGE 2 × 2 = 4

9Why is Kelvin considered the 'absolute' temperature scale?

10Two objects are placed in contact and no heat flows between them. What can you conclude?

1 = 323.15 K 2 = 26.85°C 3 = 68°F 4 = 40°C | 5 = They have greater average kinetic energy (moving faster on average) 6 = It would require removing all thermal energy, which becomes progressively harder as temperature approaches that limit (a consequence of the third law of thermodynamics) 7 = 14°F 8 = 100°C = 373.15 K | 9 = It starts at absolute zero, the true minimum possible temperature, with no negative values 10 = They are already at the same temperature (thermal equilibrium)
