NDQ_015173 | Which law states how the temperature and pressure of a gas are related? | null | a. Boyles law, b. Charless law, c. Amontonss law, d. Kinetic law | c | 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. | 0.305845 |

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. | 0.277151 |
