Chemical changes are when a new atomically bond is created or one is broken.
Physical changes are when nothing really changes, but they item changes form.
Melting ice is a physical change. The ice is still water, just not frozen.
Breaking glass is a physical change. The glass isn’t changing, its just in smaller pieces.
Filtering a mixture is a physical change. If you filter sand from water it’s still water and sand, just not together anymore.
 
Burning paper is a chemical change. When you burn the paper it is no longer paper, now it’s ash and carbon dioxide.

The fossil record of birds is incomplete because bird skeletons are
Bogdan [553]
Bird skeletons are very delicate, and therefore, difficult to be preserved.  The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.

33. Heavier loads will make the vehicle move off of the table. The heavier the weight, the quicker the  vehicle will roll. Loads that are something very similar or lighter than the vehicle won't make the vehicle move by any means.

34. Gravity is the power pulling the piano toward the Earth.

Friction would happen with an unpleasant surface, making it a lot harder to push the piano up the ramp.

35. Wagon C

Wagon C has the least boxes and minimal measure of mass, making it simplest to move.

36. I would move the crates so every cart has a similar measure of boxes, making them equivalent in mass. This would make them all take a similar measure of power to move them.
