Physical change Production of new substances Flammability Chemical change 2 / 20 A material whose particle composition allows heat & electricity to pass through it easily are described as having a high ___________. Hardness Density Conductivity Weight 3 / 20 Rust forming on a piece of iron is an example of which of the following: The natural process of decay as metallic ions age A physical change because the process can be reversed A chemical change because oxygen atoms from the atmosphere bonded with the iron atoms A violation of the laws of physics because new mass has been created 4 / 20 Maha was given a shiny golden ring as a gift for her graduation. Maha was confused about whether the ring was made of gold or plated gold. Which practical method can be followed to determine the nature of the ring without deforming it? Measure the melting point of the ring to know if it is made of real gold or plated gold. Calculate the density of the ring to know if it is made of real gold or plated gold. Measure the volume of the ring to know if it is made of real gold or plated gold. Observe the color of the ring to know if it is made of real gold or plated gold. 5 / 20 Which statements are TRUE about mass? is how much space an object takes up is the amount of matter in an object is a physical property is a chemical property 6 / 20 What is the BEST way to find the volume of the box shown in the next image? using a balance using displacement method using a graduated container using a formula ( l × w × h ) 7 / 20 Consider a solid and liquid object having the same volume. Why a solid object has a greater density than a liquid object? because the liquid can flow because the solid has a fixed volume because the particles of a liquid are closely packed in a smaller space because the particles of a solid are closely packed in a smaller space 8 / 20 Examples of Chemical Changes Combustion Burning Rusting Evaporating 9 / 20 Combining substances to form new substances is called .............. Physical reaction Chemical reaction Endothermic reaction Exothermic reaction 10 / 20 Evidence of a chemical reactions is anything that shows - interaction between 2 gases a new substance has formed a solid dissolved in a liquid a change in the state of matter 11 / 20 The displacement method is followed to determine the ................ of a solid that has an irregular shape. volume mass density shape 12 / 20 Examples of Physical Changes Evaporating Freezing Burning Grinding 13 / 20 The relationship between mass and volume is called ----------------- physical property gravity weight density 14 / 20 Which of the following statements is true? Burning paper is an example of a chemical reaction because a new substance is formed and the process cannot be undone Melting ice is an example of a chemical reaction because a new substance is formed and the process cannot be undone Cutting paper is an example of a chemical reaction because a new substance is formed and the process cannot be undone Freezing water is an example of a chemical reaction because a new substance is formed and the process cannot be undone 15 / 20 Which formula is used to calculate the density of an object? density = mass / volume density = mass + volume density = volume / mass density = volume − mass 16 / 20 This substance can be separated by physical means Pure Substances Mixtures Compounds Elements 17 / 20 What is the volume of the stone? V stone = 20 mL / 80 mL = 0 . 25 V stone = 100 mL − 80 mL = 20 mL V stone = 80 mL / 20 mL = 4 V stone = 100 mL + 80 mL = 180 mL 18 / 20 In the presence of water, iron nail reacts with oxygen in the air to produce a brownish substance called rust. Which statement is TRUE about rusting? Rusting is a physical change because there is formation of a new substance. Rusting is a physical change because the identity of the substance doesn't change. Rusting is a chemical change because there is formation of a new substance. Rusting is a chemical change because the identity of the substance doesn't change. 19 / 20 Which of the following is the best description of the results of a chemical reaction? A new substance with different properties is formed The reaction can be reversed to get back the original substance The substance seems to disappear after dissolving in water The substance changes from liquid to solid at a low temperature 20 / 20 What are the starting materials in a reaction? product reactants coefficient subscript Your score is 0% Restart quiz Go to the Quizzes Page
