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? Observe the color 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 melting point 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. 3 / 20 Which of the following statements is true? Freezing water is an example of a chemical reaction because a new substance is formed and the process cannot be undone Burning paper 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 Melting ice is an example of a chemical reaction because a new substance is formed and the process cannot be undone 4 / 20 Examples of Physical Changes Evaporating Grinding Freezing Burning 5 / 20 The displacement method is followed to determine the ................ of a solid that has an irregular shape. mass shape volume density 6 / 20 Examples of Chemical Changes Burning Rusting Combustion Evaporating 7 / 20 A material whose particle composition allows heat & electricity to pass through it easily are described as having a high ___________. Hardness Conductivity Density Weight 8 / 20 The relationship between mass and volume is called ----------------- weight physical property gravity density 9 / 20 Dissolving salt is a ............... Chemical change Physical change Flammability Production of new substances 10 / 20 What is the BEST way to find the volume of the box shown in the next image? using a graduated container using displacement method using a balance using a formula ( l × w × h ) 11 / 20 What are the starting materials in a reaction? subscript coefficient reactants product 12 / 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 chemical 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 physical change because the identity of the substance doesn't change. 13 / 20 Which of the following is the best description of the results of a chemical reaction? The substance changes from liquid to solid at a low temperature The substance seems to disappear after dissolving in water A new substance with different properties is formed The reaction can be reversed to get back the original substance 14 / 20 Which formula is used to calculate the density of an object? density = volume − mass density = volume / mass density = mass + volume density = mass / volume 15 / 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 16 / 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 chemical change because oxygen atoms from the atmosphere bonded with the iron atoms A physical change because the process can be reversed A violation of the laws of physics because new mass has been created 17 / 20 This substance can be separated by physical means Pure Substances Elements Mixtures Compounds 18 / 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 19 / 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 particles of a liquid are closely packed in a smaller space because the solid has a fixed volume because the particles of a solid are closely packed in a smaller space because the liquid can flow 20 / 20 Combining substances to form new substances is called ..............
