3. NextPrevious UNIT 11 Natural Science 1 The air is matter Home 1 First we put a crumpled piece of paper inside a glass, then we push it to the bottom in such a way that it will not fall out when we turn the glass upside down. Air occupies space

4. NextPrevious UNIT 11 Natural Science 1 The air is matter Home 2 Then we put the glass, upside down, into a container full of water. Air occupies space

5. NextPrevious UNIT 11 Natural Science 1 The air is matter Home 3 When we take the glass out we can see that the paper is dry. Why? Because the glass was full of air, so the water could not get in. Therefore, air has volume; that is, it occupies a space. Air occupies space

6. PreviousFinish UNIT 11 Natural Science 1 The air is matter Home And we can also prove that the oxygen tank of compressed air used by scuba divers is heavier when it is full of water Air has mass Then, if it is heavier this is because it has a greater mass. Therefore, air has mass and it weighs: air is matter.
