Pro Tips
Specific heat of water is 4,186 J/(kg·°C).
Specific heat of aluminum is 900 J/(kg·°C).
Positive ΔT means energy is absorbed; negative means energy is released.

Fun Facts
"It takes a lot of energy to heat water compared to most other substances."
"Absolute zero (-273.15°C) is the point where molecules stop moving almost entirely."
"The sun's energy comes from nuclear fusion, which generates immense thermal energy."
