Pascal., d. none of the above | 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. | 0.267758 |

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.

At the very north is the north pole and at the very south is the south pole of the earth. An imaginary line around the earth near the north pole is the arctic circle. It is located at 66.5 Á north of equator. An imaginary line around the earth near the south pole is the Antarctic circle. It is located at 66.5 Á south of equator. Equator is an imaginary line that goes round the Earth and divides it into two halves. The northern half is called northern hemisphere and the southern half is called southern hemisphere. Tropic of cancer and tropic of Capricorn are the two imaginary lines around the Earth on either side of the equator.
