Make a pie chart because it is the best at showing percentages. Charts are useful for organizing information because they have all the information clearly stated in front of you.
COLLISION
Surface tension is a phenomenon where liquid molecules resist an external force because if the cohesive forces between them. Neighboring molecules share the cohesive forces with the surface exhibiting stronger bonds (than below the surface). Floating needle and small insects walking on water are examples of surface tension. A collision bumps the molecules and crashes through the “film” of the surface, breaking the tension.
Ex: mixture and like you know firework which you burn the log became dust cannot be able to change back to orignial form.
