Question

In an activity in which dye was added to two beakers of water, the beaker on the hot

plate mixed the dye into the water much faster then the beaker at room temperature.
Which statement best explains why there is a difference in the speed at which the
dye mixed in the water between the two beakers.

Answer 1

If you picture water as a collection of particles, warmer water has faster moving particles, and so it should come as no surprise that these collide more frequently with the material needing to be dissolved, doing the job faster.
