11Question for Column 2 $100These are the two kinds of properties that every form of matter has. Some can be observed without changing it into another substance, and some describe its ability to change into different substances.
12Physical and Chemical Properties Column 2 Answer $100Physical and Chemical Properties
13Question for Column 2 $200This is a physical property that describes how much matter is in an object.
17Question for Column 2 $400Gold miners would use this property of matter to determine if they had discovered real gold. They could determine this if they knew the mass and volume of the item they found, since this property tells us how much mass is packed in a certain volume.
18Column 2 Answer $400 Density The cube on the left is more dense, since it has more mass packed into the same volume.
19Question for Column 3 $100This state of matter has a definite shape and a definite volume. Its molecules are arranged in tight, orderly formations.
21Question for Column 3 $200This state of matter has no definite shape and no definite volume. In fact, its fast moving, wildly arranged molecules can actually be compressed if we need to fit them in a smaller container.
23Question for Column 3 $300When a substance changes from a gas to a liquid, the speed of its molecules does this, and so does the distance between its molecules.
24The speed decreases and so does the distance between the molecules. Column 3 Answer $300The speed decreases and so does the distance between the molecules.
25Question for Column 3 $400Thermal energy is the total energy of the motion of all the particles in an object. When thermal energy is transferred, it always moves from _______ matter to _______ matter.warmer/cooler warmer/cooler
26Column 3 Answer $400Thermal energy always moves from warmer matter to cooler matter.
27Question for Column 4 $100The Law of Conservation of Mass states that matter is not created or destroyed in any chemical or physical change. So, after the methane and oxygen react to make carbon dioxide and water, how many total atoms will there be?
28Column 4 Answer $100There will still be 9 total atoms, even though they will be arranged differently.
29Question for Column 4 $200This is water, with a density of 1 gram per cubic centimeter. Give one possible number that could represent the density of the red liquid.
30Column 4 Answer $200Its density could be any number between 0 and 1. It is less than 1 gram per cubic cm, because less dense matter floats.
31Question for Column 4 $300 This mineral sample has a mass of 126 g and a volume of 15 cm3. What is its density?
32Column 4 Answer $300Density = 𝑚𝑎𝑠𝑠 𝑣𝑜𝑙𝑢𝑚𝑒 , so its density is 8.4 g per cm3.By the way, it’s not gold. Gold’s density is 19.3 grams per cm3.
33Question for Column 4 $400The line graph shows the temperature change for a glass of water, when ice was added. Use your knowledge of matter and thermal energy to explain what happened.
34Column 4 Answer $400The temperature of the water dropped, because the warmer water lost its heat to the colder ice.
