Question
When a rectangular glass tube filled with water is heated as shown, which direction does a few drops of dye at X move?
1 point
Solution
When a rectangular glass tube filled with water is heated, the following occurs:
- Heat Transfer: The water at the bottom of the tube is heated, causing it to expand and become less dense.
- Convection Currents: As the water at the bottom becomes less dense, it rises to the top, while the cooler, denser water moves down to replace it.
- Movement of Dye: The few drops of dye at point X, which are in the path of the rising warmer water, will move upward due to this convection process.
Final Answer
The drops of dye at point X move upward.
