NDQ_018026 | plasma is more similar to gases than to liquids or solids. | null | a. true, b. false | a | DD_0238 | image | teaching_images/evaporation_and_sublimation_8074.png | The image below shows the different changes in states of matter. A material will change from one state or phase to another at specific combinations of temperature and surrounding pressure. Typically, the pressure is atmospheric pressure, so temperature is the determining factor to the change in state in those cases. The names of the changes in state are melting, freezing, boiling, condensation, sublimation and deposition. The temperature of a material will increase until it reaches the point where the change takes place. It will stay at that temperature until that change is completed. Solids are one of the three phase changes. Their structure and their resistance to change their shape or volume characterize solids. In a solid, the molecules are closely packed together. Liquids are the next of the three phase changes. Liquids are very different from solids, their structure is a bit freer, but not as free as gas. In a liquid phase, the molecules will take the shape of its container or the object that it is in. Gases are the last of the three phase changes. A gas phase is one of the simpler phases, because the gas molecules are the freest. This is because theoretically the molecules behave completely chaotically and they roam anywhere and fill every space of an object or container. | 0.289964 |

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. | 0.285929 |

Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. For a solid to change to a liquid, matter must absorb energy from its surroundings. Freezing happens when the water cools and loses energy until they remain in fixed positions as ice. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition. | 0.272268 |

NDQ_018114 | a solute generally raises the freezing point of a solvent. | null | a. true, b. false | b | DD_0236 | image | teaching_images/state_change_7605.png | This diagram shows the changes of state in matter. Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matters chemical makeup or chemical properties. They occur when matter absorbs or loses energy. Processes in which matter changes between liquid and solid states are freezing and melting. For a solid to change to a liquid, matter must absorb energy from its surroundings. Freezing happens when the water cools and loses energy until they remain in fixed positions as ice. Processes in which matter changes between liquid and gaseous states are vaporization, evaporation, and condensation. Processes in which matter changes between solid and gaseous states are sublimation and deposition. | 0.290747 |
NDQ_018114 | a solute generally raises the freezing point of a solvent. | null | a. true, b. false | b | DD_0240 | image | teaching_images/evaporation_and_sublimation_6875.png | There are 4 states of matter observable in everyday life: solid, liquid, gas and plasma. This diagram shows 3 of these states: solid, liquid and gas and the processes that cause matter to change states. When a gas changes to a liquid, a liquid changes to a solid or a gas changes to a solid, heat is given out. Conversely, when a solid changes to a liquid, a liquid changes to a gas and a solid changes to a gas, heat is taken in. The names of these processes are provided in the diagram. For example: the process of state change from gas to liquid is called condensation. The process of change from liquid to solid is called freezing. The process of change from solid to liquid is called melting and the process of change from solid to gas is called sublimation. | 0.290731 |

NDQ_018114 | a solute generally raises the freezing point of a solvent. | null | a. true, b. false | b | 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. | 0.680088 |
NDQ_018114 | a solute generally raises the freezing point of a solvent. | null | a. true, b. false | b | T_4883 | text | null | Specific heat is a measure of how much energy it takes to raise the temperature of a substance. It is the amount of energy (in joules) needed to raise the temperature of 1 gram of the substance by 1 C. Specific heat is a property that is specific to a given type of matter. Thats why its called specific. | 0.674986 |

NDQ_018114 | a solute generally raises the freezing point of a solvent. | null | a. true, b. false | b | T_4783 | text | null | Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster. If you dont stir the iced tea, the sugar may eventually dissolve, but it will take much longer. | 0.662673 |
