If an object is denser than water, what will happen when it is placed in water?

• It will float

• It will sink

• It will neither float nor sink

• It will dissolve

Which factor does NOT affect whether an object will float or sink?

• The object's mass

• The object's density

• The volume of water

• The object's shape

How does the shape of an object affect its buoyancy and ability to float in water?

• The shape of an object does not affect its buoyancy; only its material matters.

• Shaping an object increases its mass, making it float.

• The shape of an object determines how much water it displaces, which affects its buoyancy.

• Objects always float if they are hollow, regardless of their shape.

What role does the density of the liquid play in determining whether an object will sink or float?

• The density of the liquid does not affect whether an object sinks or floats.

• Higher density liquids provide greater buoyant force, making it easier for objects to float.

• Objects always float in any liquid, regardless of its density.

• Lower density liquids make objects more likely to float.

Which sentence is TRUE?

• Small objects always float

• Big , heavy object always sink

• An object sink if the density is greater than the water

• When an objects floats, it fall to the bottom

An expired egg will sink

• True

• False
