Answer:
The weight of the plane is (mass) x (acceleration of gravity).
Neither of these changes when the plane rises from the ground.
Its weight on the ground is equal to (the same as) its weight in the air.
Answer:
Water is not a good solvent choice.
Explanation:
While water is good solvent because of its polotiry.

Water has the dissolves when warm part down. But for the cooled part which is the most important it can not do.
No, they do not. Hope I helped! :)
