3. The effect of buoyant force when an object floats, sinks, or hovers in a fluid.
6. The mass per unit of volume for a substance.
7. in the fluid To remain suspended in the fluid without rising to the surface or sinking.
8. To stay on the surface of a fluid without sinking.
9. To go down or submerge in a fluid because it is denser than the fluid.
11. The 3D space that is occupied by an object.
12. The upward force exerted by a fluid on an object placed in it, which makes the object float or appear lighter.
13. A state of matter in which the molecules of a substance are close together but free to move relative to each other. Has a definite volume but no definite shape.
17. A compartment in a ship or submarine that can be filled with water or air to control buoyancy and stability.
18. Air that is confined in a space and forced to a higher pressure than the surrounding atmosphere.
20. Having a higher density than another substance, so it tends to sink in a fluid.

1. Having a lower density than another substance, so it tends to float in a fluid.
2. The rules that explain how and why objects float, sink, or hover in a fluid, based on the relationship between the object's density and the fluid's density.
4. The amount of matter in an object (usually measured in grams).
5. A statement about what you think will happen in an experiment or situation based on prior knowledge or evidence.
10. An internal gas-filled organ in fish that helps them control buoyancy and maintain their depth in water.
14. A material that has its own specific properties and composition, different from other substances.
15. A state of matter in which the molecules of a substance are widely separated and can move freely. Has no definite shape or volume.
16. A substance that can flow and take the shape of its container, including liquids and gases.
19. The upward force exerted by a fluid on an object immersed in it, opposing the object's weight.
