What is Matter? If you add an object to water, the water level will rise. That is because the object takes up space. In this case, it is the ice cube that takes up space. Measuring Volume of Liquids volume- the volume of an object is the space it takes up The unit of volume for a liquid is ml The unit of volume for a solid is cc (cubic centimeter) Feb 20 8:59 M Feb 20 9:33 M Mass and Matter Weight the amount of matter in an object anything that has mass and volume a balance can be used to measure mass Is there a difference in weight? Weight is how strongly gravity pulls on an object Yes! Feb 20 9:37 M Feb 20 9:40 M Weight and Mass volume, mass, and weight are all Physical Properties (we can sense these properties with touch, taste, smell, & sight) on Earth The mass of the bowling ball would be the same. The weight would be different, because the moon's gravity is weaker. on moon and we can measure them with balances, graduated cylinders, and scales Feb 20 9:57 M Feb 20 10:14 M 1
States of Matter-three forms matter can take hanging States of Matter determines change solid In a solid, the particles line up in an organized pattern melting point- is when a solid turns into a liquid liquid In a gas, the particles move very rapidly. They are spread out with a lot of empty space. In a liquid, the particles move past one another, but they remain close together. gas evaporation (all temps) vaporization-the change from liquid to gas boiling point (one temp) 212 degrees F 100 degrees Feb 20 10:21 M Feb 20 10:36 M hanging States of Matter determines change ensity is the measure of how tightly matter is packed in an object condensing- is when a gas turns into a liquid less dense than water cork freezing-the change from liquid to solid 32 degrees F 0 degrees more dense than water rock sublimation- the change from a solid to a gas Feb 20 10:36 M Feb 20 11:24 M Properties of Matter 1 What is matter? Grade: Subject: Science ate: how strongly gravity pulls on an object the volume of an object volume and mass of an object the weight of an object Feb 20 11:38 M 2
2 What is the difference of weight and mass of a marble on the Earth and moon? 3 How are particles lined up in a solid? they do not change particles are lined up in an organized pattern and do not move much only the mass changes only the weight changes they both change particles are lined up but have freedom to move past one another particles are not lined up at all, and they moved rapidly there are no particles 4 Which of the following diagrams represent the particles in a gas 5 Which of the following diagrams represent the particles in a solid 6 Which of the following diagrams represent the particles in a liquid 7 The following picture is an example of the melting point. True False 3
8 The following picture is an example of condensation. 9 What is vaporization? True False 10 What is freezing? 11 What is sublimation? 12 Evaporation and boiling point both occur in what? 13 The changes in the states of matter depend on what variable? sublimation environment condensing altitude freezing time of day vaporization 4
14 What is density? 15 Which of the following is not a physical property of matter? a measure of how tightly matter is packed in an object a measure of the mass of an object volume mass a measure of the weight of an object weight not here Thank You! Feb 20 1:02 PM 5
