Question

cheryl has a mug that she says is made up of matter. heather says that the hot chocolate inside the cup is made up of matter, too. keaton says that the steam coming from the cup is also made up of matter. mikayla says that none of it is matter because matter is too small to see. which best describes who is correct?

• cheryl
• cheryl, heather, and keaton
• cheryl and heather
• mikayla

Explanation:

Matter is anything that has mass and takes up space. The mug (solid), hot chocolate (liquid), and steam (gas, water vapor) all have mass and occupy space, so they are matter. Cheryl (mug), Heather (hot chocolate), and Keaton (steam) are all correct. Mikayla is wrong as matter can be seen (like the mug, hot chocolate) or not (like steam, but steam is still matter).

Answer:

Cheryl, Heather, and Keaton
