• They will change shape to fit a container and have definite volume.

• They have definite volume and have atoms that move freely in all directions.

Which statement summarizes the difference between mass and weight?

• Mass is the downward pull on an object due to gravity, and weight is the amount of matter in an object.

• Mass is the amount of matter in an object, and weight is the downward pull on an object due to gravity.

• Mass is measured in newtons, and weight is measured in pounds.

Uranium is a type of atom. In special circumstances that usually involve high amounts of energy, uranium can be broken. When this occurs, different pieces of the original atom remain, including a substance called plutonium.

Which statement most likely describes plutonium?

• It will still be uranium, just smaller pieces of uranium.

• It must no longer be a form of matter.

• It must be a different kind of atom.

• It will be different than, but have the same properties as, uranium.
