Question

3. Which of the following is true about an object that floats in water? (1 point)
The object is less dense than frozen water.
The mass of the object is less than that of water.
The density of the object is less than that of water.
The volume of the water is greater than the object’s volume.

Answer 1

Do you know what measurement we depend on to see if an object floats in water? In other words, do we look at the mass, density, or volume? That's a good place to start.
Volume is about how much space the object takes up. Mass is about how much matter the object contains. Density is the ratio of mass to volume -- in other words, how densely packed the object is.
Which of these seems like it would give you enough information to tell whether an object would sink or float?
