HELP ME PLEASE A sunflower seed is buried in soil and watered. Soon, the seed grows strong enough to break out of its seed coat.

What is true of the forces involved as the seed emerges from the top of the
seed coat?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
