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:

Matter is defined as anything that has mass and takes up space (volume). Michelle's statement is incorrect because matter doesn't have to be visible (e.g., air). Evan's statement is wrong as matter doesn't have to be touchable (e.g., some gases). Leon's statement is incomplete as matter must also take up space. Ricky's statement aligns with the scientific definition of matter (mass and takes up space).

Answer:

B. Ricky
