Select the correct answer:

A drop of ink is added to a beaker of cold water. The colour spreads, but very slowly. When the same is done with hot water, the colour spreads much faster. This observation most strongly supports that:

Particles move faster when their kinetic energy increases
Particles have fixed positions in water
Particles have no spaces between them
Particles of ink and water repel each other
