ANS: Mass is the quantity of matter that makes up an object. Volume is the quantity of space that an object takes up. PTS: 1 TOP: Chemistry DIF: Easy OBJ: Section 4.2 KEY: mass | volume 6 STA: PS-C-03 MSC: Knowledge ID: A 75. ANS: During a physical change, a material may change its shape or state, but it keeps its identity. During a chemical change, one type of matter changes to produce one or more different types of matter. PTS: 1 DIF: Average OBJ: Section 4.3 STA: PS-C-03 TOP: Chemistry KEY: physical change | chemical change MSC: Knowledge 76. ANS: Qualitative properties are those that you can observe directly with your senses. Quantitative properties are those that you can measure or describe with a numerical value. Examples will vary. Possible examples are: Qualitative: colour, odour, shape Quantitative: temperature, melting point, boiling point PTS: 1 DIF: Average OBJ: Section 4.1 STA: PS-C-03 TOP: Chemistry KEY: qualitative property | quantitative property MSC: Knowledge 77. ANS: Baking a cake is a non-reversible chemical reaction. The ingredients are changed into other materials with properties that are different from the properties of the original materials. PTS: 1 DIF: Average OBJ: Section 4.3 STA: PS-C-03 TOP: Chemistry KEY: chemical change | non-reversible MSC: Knowledge 78. ANS: In a solid, the particles are packed closely together and do not move (but they rotate and vibrate). This is why a solid keeps its shape in any container. In a gas, the particles have large spaces between them and are able to move from one place to another. This is why a gas take up the shape of the container it is in. PTS: 1 DIF: Difficult OBJ: Section 4.3 TOP: Chemistry KEY: particle model of matter 79. ANS: Responses will vary. Possible examples are: solid state — steel, bronze, brass liquid state — tea, vinegar, honey gas state — air PTS: 1 TOP: Chemistry DIF: Easy OBJ: Section 5.2 KEY: homogeneous | mixture 7 STA: PS-C-02 MSC: Knowledge STA: PS-C-02 MSC: Skills
