Ice wedging happens because water expands as it goes from liquid to solid. When the temperature is warm, water works its way into cracks in rock. When the temperature cools below freezing, the water turns to ice and expands. The ice takes up more space. Over time, this wedges the rock apart. Ice wedging is very effective at weathering. You can find large piles of broken rock at the base of a slope. These rocks were broken up by ice wedging. Once loose, they tumbled down the slope. | 0.300817 |

NDQ_014129 | A graduated cylinder is used to measure the volume of liquids. | null | a. true, b. false | a | T_3918 | text | null | Some properties of matter can be measured or observed only when matter undergoes a change to become an entirely different substance. These properties are called chemical properties. They include flammability and reactivity. | 0.671306 |
NDQ_014129 | A graduated cylinder is used to measure the volume of liquids. | null | a. true, b. false | a | T_3960 | text | null | Solids that change to gases generally first pass through the liquid state. However, sometimes solids change directly to gases and skip the liquid state. The reverse can also occur. Sometimes gases change directly to solids. | 0.652145 |

NDQ_014129 | A graduated cylinder is used to measure the volume of liquids. | null | a. true, b. false | a | T_3946 | text | null | For a given amount of gas, scientists have discovered that the pressure, volume, and temperature of a gas are related in certain ways. Because these relationships always hold in nature, they are called laws. The laws are named for the scientists that discovered them. | 0.640794 |
NDQ_014129 | A graduated cylinder is used to measure the volume of liquids. | null | a. true, b. false | a | T_4893 | text | null | A given kind of matter has the same chemical makeup and the same chemical properties regardless of its state. Thats because state of matter is a physical property. As a result, when matter changes state, it doesnt become a different kind of substance. For example, water is still water whether it exists as ice, liquid water, or water vapor. | 0.634767 |

NDQ_014129 | A graduated cylinder is used to measure the volume of liquids. | null | a. true, b. false | a | T_3912 | text | null | Mass is the amount of matter in a substance or object. Mass is commonly measured with a balance. A simple mechanical balance is shown in Figure 3.1. It allows an object to be matched with other objects of known mass. SI units for mass are the kilogram, but for smaller masses grams are often used instead. | 0.623839 |
