  1. 1.

    According to the particle model of matter, why does a drop of food coloring spread more rapidly in hot water than in cold water?

    • A) The water particles expand in size, pushing the coloring particles aside more rapidly.
    • B) The particles have higher average kinetic energy and move faster, leading to more rapid mixing.
    • C) The particles lose their random motion and flow in a single direction toward areas of low concentration.
    • D) The attractive forces between the liquid particles become stronger, pulling the dye through the liquid.
