[Q]: Please answer correctly the following question related to the paragraph below. Which person must have decreased the temperature of their reaction? Thomas and Alexander are freshman students in an introductory chemistry laboratory course at their local college. In this week's experiment, both Thomas and Alexander will be starting their experiments with liquid water. They both follow different experimental protocols, and at the end of the experiment Thomas discovers ice in his reaction flask, while Alexander discovers steam in his reaction flask. Hint: As Figure above shows, the distance between particles is much smaller for the solid and liquid states than for the gas state. In the solid state, particles are fixed in place, while particles are more free to move in the liquid and gas states. The particles in the solid and liquid states "stick together," but in the gas state, they move freely about the container. In general, it requires energy to separate individual particles. If we want to make a solid adopt a liquid form, we can add energy in the form of heat, increasing the temperature of the substance. Conversely, if we want to convert a substance from a gas to a liquid or from a liquid to a solid, we remove energy from the system and decrease the temperature. Pressure also plays an important role in changes of state, which will be discussed later on. We will study these difference in greater detail in the chapter States of Matter.

[Q]: Please answer correctly the following question related to the paragraph below. Which farm prevented the crop from toppling? Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project. Hint: Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts.

[Q]: Please answer correctly the following question related to the paragraph below. Which color rock is more likely to be thinner? Martha is currently walking around the forest when she notices two rocks that catch her attention. She quickly picks them up, stows them in her backpack and runs to the local geologist. She shows them to Linda, the geologist, and asks what she can tell her about the rocks. Linda informs her that the yellow rock has been subject to horizontal compression, but the blue rock has not been horizontally compressed. She promises Martha she will look into the rocks in more detail to answer more questions for her. Hint: When rock units are placed under horizontal compression, they shorten and become thicker. Because rock units, other than muds, do not significantly change in volume, this is accomplished in two primary ways: through faulting and folding. In the shallow crust, where brittle deformation can occur, thrust faults form, which causes deeper rock to move on top of shallower rock. Because deeper rock is often older, as noted by the principle of superposition, this can result in older rocks moving on top of younger ones. Movement along faults can result in folding, either because the faults are not planar or because rock layers are dragged along, forming drag folds as slip occurs along the fault. Deeper in the Earth, rocks behave plastically and fold instead of faulting. These folds can either be those where the material in the center of the fold buckles upwards, creating "antiforms", or where it buckles downwards, creating "synforms". If the tops of the rock units within the folds remain pointing upwards, they are called anticlines and synclines, respectively. If some of the units in the fold are facing downward, the structure is called an overturned anticline or syncline, and if all of the rock units are overturned or the correct up-direction is unknown, they are simply called by the most general terms, antiforms and synforms.

[Q]: Please answer correctly the following question related to the paragraph below. Which friend lives closer to Lanai island? Two old friends Mary and Ann lived thousands of miles away. Mary lived on the Big Island of Hawaii, while Ann lived in Boston. Mary visited Boston, while Ann has never been to Hawaii. Hint: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loihi seamount. Loihi is the youngest volcano. Hawaii is a fantastic place to see volcanic eruptions and features.
