The students in ms. hill's science class were investigating the properties of water. they placed a piece of celery in a beaker of blue water. the next day, the celery was no longer green, but blue, all the way up to the leaves. what property of water best explains why the blue water moved up the celery stalk? a) buoyancy b) specific heat c) surface tension d) capillary action

A and B can be eliminated. Buoyancy has to do with things floating on water and there's no heat involved with this experiment, so those two answers are wrong.

We're left with C and D. There is no surface tension involved, so the answer would be letter D - capillary action. Capillary action is what happens when water is forced up the walls of a vessel. Capillary action caused the celery to turn blue.

D

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun
