NDQ_015192 | There is an inverse relationship between gas pressure and temperature. | null | a. true, b. false | b | 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. | 0.292905 |

Because fluid flows from an area of high to low pressure, the drink moves up the straw and into your mouth. When you breathe, a muscle called the diaphragm causes the rib cage and lungs to expand or contract. When they expand, the air in the lungs is under less pressure than the air outside the body, so air flows into the lungs. When the ribs and lungs contract, air in the lungs is under greater pressure than air outside the body, so air flows out of the lungs. | 0.326028 |

NDQ_015196 | Cooling a gas in a closed container causes its pressure to decrease. | 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. | 0.708186 |
NDQ_015196 | Cooling a gas in a closed container causes its pressure to decrease. | null | a. true, b. false | a | T_3939 | text | null | Water vapor is an example of a gas. A gas is matter that has neither a fixed volume nor a fixed shape. Instead, a gas takes both the volume and the shape of its container. It spreads out to take up all available space. You can see an example in Figure 4.6. | 0.704248 |
NDQ_015196 | Cooling a gas in a closed container causes its pressure to decrease. | 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. | 0.689134 |
NDQ_015196 | Cooling a gas in a closed container causes its pressure to decrease. | null | a. true, b. false | a | T_4174 | text | null | Vaporization is easily confused with evaporation, but the two processes are not the same. Evaporation also changes a liquid to a gas, but it doesnt involve boiling. Instead, evaporation occurs when particles at the surface of a liquid gain enough energy to escape into the air. This happens without the liquid becoming hot enough to boil. | 0.664243 |
