__________ is the amount of space taken up by an object.
What is volume?
_______ means to be able to bend or pound into shapes.
What is malleable/Malleability?

What is a characteristic property? Do they change when you change the sample of the substance?
__________ is the amount of matter in an object.
What is mass?
What is the difference between a chemical property and a physical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. A chemical property describes the ability of a substance to undergo a specific chemical change.
