Selena performs an experiment to determine if air is made of matter. She takes the mass of a syringe that is vacuum sealed and then re-takes the mass of the syringe when the vacuum seal is broken. Below are her results. What can she conclude from her experiment?

• Yes, air is matter because it has both volume and mass

• No, air is not matter it only has volume but no mass

• No, air is not matter it only has mass but no volume

• Yes, air is matter because it has either mass or volume
