Similar ACT Doubts

Both gases and liquids are considered to be fluids that have individual molecules that move around with kinetic and potential energy. Kinetic energy, defined as the energy related to motion, takes three forms: translational energy that occurs as a molecule moves from position A to position B, rotational energy that occurs as a molecule spins around an imaginary axis at its center of mass, and vibrational energy that occurs as individual atoms in a molecular bond move towards and away from each other. Usually, molecules possess varying combinations of kinetic energy forms. In contrast, potential energy is defined as stored energy that could be released to become kinetic energy. The total energy of a molecule is fixed, meaning that a molecule has some combination of kinetic and potential energies.Varying amount of kinetic and potential energies define how molecules in a fluid interact with each other. For example, when the kinetic energy of a molecule is high (greater than 1000J), it can no longer interact with neighboring molecules strongly enough to remain a liquid. However, if the potential energies are too high (greater than 1000 J), molecules cannot escape a liquid to become a gas. If the kinetic energy is high and the potential energy is low, molecules tend to become a gas and can be modeled by an equation known as the Ideal Gas Law:PV=nRT Where P is the pressure of a gas, V is the volume, n is the number of moles of a gas, R is a constant, and T is temperature in degrees Kelvin.The Ideal Gas Law perfectly applies to particles with no mass, no intermolecular interactions, and no true volume. However, real molecules do not adhere perfectly to the Ideal Gas Law.Q. As the kinetic energy of a molecule increases, one would expect the potential energy to

Directions: Read the passages and choose the best answer to each question.PassageSOCIAL SCIENCE: This passage discusses some social and economic issues regarding liquid natural gas as an energysource.Although oil and gasoline remain importantenergy sources, it is natural gas that currently suppliesaround 25 percent of America’s energy needs. A recentstudy shows that natural gas use was roughly 22 trillion(5) cubic feet (TCF) annually. Natural gas demand isincreasing at phenomenal rates because of its abilityto create cleaner fuel for electrical power. Experts pre-dict that annual demand is likely to increase to almost32 TCF in less than a decade. At a consumption rate(10) of 32 TCF per year, the United States would only haveabout a five-year supply of natural gas. Known naturalgas reserves in North America are quickly becomingexhausted. In fact, in the past thirty years, known sup-plies have dwindled from almost 300 TCF to around(15) 150 TCF.It is no wonder that natural gas has become a con-troversial and critical topic of discussion among politi-cians, business leaders,and consumers. It is apparentthat the United States will need to drastically increase(20) imports of natural gas to relieve shortages. One waythat economists believe this can be done is by importingliquid natural gas. Experts predict that liquid naturalgas imports will increase by almost 500 percent in a fewshort years. Currently, the country imports very little(25)liquid natural gas. The process of transporting liquidnatural gas is complicated and expensive. This is themost obvious reason why America has been reluctantto choose liquid natural gas over other energy sources.Converting natural gas into liquid natural gas involves(30) cooling natural gas as it is collected to −260F. Thistransforms the gas into a liquid, which is then injectedinto a specially designed vessel for transport. Whenthe liquid natural gas reaches its destination, the liquidis reheated into its original gaseous state and allowed(35) to flow into a pipeline. Even though new technologyhas considerably decreased transportation costs for liq-uid natural gas, it is still often uneconomical. This isespecially true for nations with other energy sources.One of the largest misconceptions about liquid(40) natural gas is that it is an abundant source of naturalgas. While liquid natural gas imports continue toincrease, the public demand for natural gas increasesat an even higher rate. Even though the United Stateshas several facilities that can process liquid natural gas,(45) these facilities are consistently unable to obtain enoughliquid natural gas to operate at their fullest capacity.Even when liquid natural gas is obtainable, there is afear that low natural gas prices in the United States willmake liquid natural gas uneconomical. Most business(50) leaders and politicians are reluctant to create new facili-ties to process liquid natural gas because these facilitiesare expensive and risky. This limits the capacity to pro-cess liquid natural gas even if it becomes more readilyavailable.(55) The United States also faces competition fromAsia in securing liquid natural gas. Competition forliquid natural gas will most likely become even moreferocious as other populous countries like Japan andChina become more desperate for fuel sources. Some(60) of the more daring politicians and business leadersbelieve that building new liquid natural gas facilitieswill help companies and consumers take advantage offuture increased liquid natural gas imports. Currently,Canada is the largest liquid natural gas supplier for(65) the United States. However, liquid natural gas importsfrom Canada will decrease considerably in the nextdecade as Canadian consumption increases and sup-plies of natural gas dwindle. Therefore, consumers andbusiness leaders should not rely on liquid natural gas(70) to solve America’s energy needs and consumers shouldcontinue to expect high prices as demand grows andsupplies decline.Q.The author of the passage would most likely agree with which of the following statements?

Chemists can model how solids, liquids, and gases behave at different temperatures and pressures with a graph called a phase diagram. When the pressure and temperature are simultaneously known, a scientist can predict whether the material will be in a specific state. The diagram is divided into sections depending on the phase and the lines between sections represent phase transitions occurring between two or more separate phases.In general, solids of neatly stacked molecules exist when temperatures are low and pressures are intermediate. These values decrease the kinetic energy of the molecules enough to allow for attractive forces to begin the stacking process. Liquids, by contrast, are found at intermediate pressures and temperatures. The temperature is high enough to impart enough kinetic energy to prevent solid formation and the pressure is high enough to prevent the liquid from becoming a gas. Finally, a gas forms at low pressures and high temperatures. The high level of kinetic energy prevents molecules from associating with one another.Materials can undergo processes called phase transitions, meaning they can transition from one phase to another. The transition from a solid to a liquid is called melting, while the reverse transition is called freezing. Vaporization occurs when a liquid becomes a gas, while condensation occurs when a gas becomes a liquid. Finally, in a process called sublimation, a solid can directly become a gas without passing through a liquid phase. Additionally, when a gas directly becomes a solid, this is known as deposition.Q.According to the figure, the material represented by area three is in what phase?
