that moves the red dye? What is the energy source that moves the blue dye?

1 answer

The energy source that moves the red dye could be a physical force such as gravity, mechanical force from stirring, or a chemical reaction. The specific energy source would depend on the context.

Similarly, the energy source that moves the blue dye would also depend on the context. It could be a physical force, mechanical force, or a chemical reaction.
