Which of the following best defines matter?
A
Anything that emits light
B
Anything that is a solid or a liquid
C
Anything that can be seen with the naked eye
D
Anything that has mass and occupies space
Verified step by step guidance1
Understand that matter is a fundamental concept in chemistry and physics, referring to anything that has mass and takes up space.
Recognize that matter is not limited to solids and liquids; gases and plasma are also forms of matter because they have mass and occupy space.
Note that emitting light is a property of some matter (like stars) but not a defining characteristic of all matter.
Realize that visibility to the naked eye is not a criterion for matter, as many forms of matter are microscopic or invisible but still have mass and volume.
Conclude that the best definition of matter is 'anything that has mass and occupies space' because it encompasses all physical substances regardless of their state or visibility.
