Thermal Energy and Heat Transfer.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Color changes mean atoms are rearranging — even if you can't see them.
Mind = Blown
🧪 If you could remove all the empty space from atoms, the entire human race would fit in a sugar cube.
Make a hypothesis first
Before you mix: what color do you think it'll turn?
What You'll Learn
Thermal energy transfers from warmer objects to cooler ones through conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves).
