Question

evan and his friends are working on a group project on matter. michelle says that matter is anything that has mass. ricky says matter must have mass and also be touchable. evan thinks matter must have mass and also be visible. leon disagrees and says that matter has both mass and takes up space. who is correct?
a. michelle
b. ricky
c. evan
d. leon

Explanation:

The scientific definition of matter is anything that has mass and takes up space (volume). Michelle only mentions mass, missing the space - occupying aspect. Ricky's "touchable" is incorrect (e.g., air is matter but not touchable in the way he means). Evan's "visible" is wrong (e.g., air or some gases are matter but not visible). Leon's description matches the scientific definition of matter.

Answer:

D. Leon
