Does the shape of the object determines how fast it sinks in water?
No. Buoyancy depends only on total volume of water displaced and the mass of the object, not the shape of the displacement. However, if the change in the shape affects the volume of water displaced, then the bouyancy of the object is affected. Scuba divers with wet suits know that the volume of their wet suit compresses as their depth increases, causing the suit (and the diver) to become less bouyant.
Does the buoyant force on a submerged object depend on the weight of the object itself or on the weight of the fluid displaced by the object?
The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.
Does amount of water affect how fast it freezes?
no slenderman not
What two factors can affect an objects kinetic energy?
How fast an object is moving and its mass. Resources: Textbook
How does raising the temperature of an object affect its density?
When you raise the temperature the molecules in the object start to move fast and bounce off one another. They start to move further apart. So the density of the object decreases.

How does the density of an object that sinks into a fluid compare to the density of the fluid?
Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
Will a shape of an object affect how fast it falling?
In air, yes. In vacuum, no.
Does salt affect how fast or slow water freezes?
yes it does it does not freeze as fast

The upward bouyant force depends only on the weight of the displaced fluid. The NET force (object's weight - bouyant force) depends on the object's weight and will determine how fast it sinks.
Does temperature affect how fast water evaporates?
Yes.
Does amount of water affect how fast it freezes?
no slenderman not
Does the water temperature affect how fast the balloon fills up?
No
Does water temperature affect how fast the rocket launches?
yes it does
Does the thickness of a container affect how fast water freezes?
No not really

Will sugar affect how fast water evaporates?
Pure water is evaporated faster than water with sugar.
