Q: What does increased temperature do to a substance's kinetic energy? Read this paragraph and choose the correct option from the provided answers: Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. The faster moving particles have more disorder than particles that are moving more slowly at a lower temperature. Choices: - generates - nothing - decreases - increases A:
increases

Q: What do rocket-based systems use to propel itself into space? Read this paragraph and choose the correct option from the provided answers: The space shuttleand any other rocket-based systemuses chemical reactions to propel itself into space and maneuver itself when it gets into orbit. The rockets that lift the orbiter are of two different types. The three main engines are powered by reacting liquid hydrogen with liquid oxygen to generate water. Then there are the two solid rocket boosters, which use a solid fuel mixture that contains mainly ammonium perchlorate and powdered aluminum. The chemical reaction between these substances produces aluminum oxide, water, nitrogen gas, and hydrogen chloride. Although the solid rocket boosters each have a significantly lower mass than the liquid oxygen and liquid hydrogen tanks, they provide over 80% of the lift needed to put the shuttle into orbitall because of chemical reactions. Choices: - water reactions - hydrogen reactions - nuclear reactions - chemical reactions A:
(Answer)
chemical reactions

Ques: Q: In hypothesis-based science, specific results are predicted from a general premise, which is called what type of reasoning that proceeds from general to particular? Read this paragraph and choose the correct option from the provided answers: lecture. One observation to explain this occurrence might be, "When I eat breakfast before class, I am better able to pay attention. " The student could then design an experiment with a control to test this hypothesis. In hypothesis-based science, specific results are predicted from a general premise. This type of reasoning is called deductive reasoning: deduction proceeds from the general to the particular. But the reverse of the process is also possible: sometimes, scientists reach a general conclusion from a number of specific observations. This type of reasoning is called inductive reasoning, and it proceeds from the particular to the general. Inductive and deductive reasoning are often used in tandem to advance scientific knowledge (Figure 1.7). Choices: - reactive - transitive - reflexive - deductive A:
Ans: deductive

Q: The reaction of calcium oxide with carbon dioxide forms what? Read this paragraph and choose the correct option from the provided answers: The way in which a reaction is written influences the value of the enthalpy change for the reaction. Many reactions are reversible, meaning that the product(s) of the reaction are capable of combining and reforming the reactant(s). If a reaction is written in the reverse direction, the sign of the changes. For example, we can write an equation for the reaction of calcium oxide with carbon dioxide to form calcium carbonate. Choices: - nitrogen carbonate - carbon monoxide - nitrogen - calcium carbonate A:
(A).
calcium carbonate

Ques:Q: What results when gas particles rebound off the walls of their container? Read this paragraph and choose the correct option from the provided answers: Pressure is what results when gas particles rebound off the walls of their container. The basic unit of pressure is the newton per square meter (N/m2). This combined unit is redefined as a pascal (Pa). One pascal is not a very large amount of pressure. A more useful unit of pressure is the bar, which is 100,000 Pa (1 bar = 100,000 Pa). Other common units of pressure are the atmosphere (atm), which was originally defined as the average pressure of Earth's atmosphere at sea level; and mmHg (millimeters of mercury), which is the pressure generated by a column of mercury 1 mm high. The unit millimeters of mercury is also called a torr, named after the Italian scientist Evangelista Torricelli, who invented the barometer in the mid1600s. A more precise definition of atmosphere, in terms of torr, is that there are exactly 760 torr in 1 atm. A bar equals 1.01325 atm. Given all the relationships between these pressure units, the ability to convert from one pressure unit to another is a useful skill. Choices: - light - pull - weight - pressure A:

Ans:pressure

Q: What is likely to happen to a parasite if it kills its host? Read this paragraph and choose the correct option from the provided answers: Some parasites kill their host, but most do not. It's easy to see why. If a parasite kills its host, the parasite is also likely to die. Instead, parasites usually cause relatively minor damage to their host. Choices: - it thrives - it adapts - it mutates - it dies A:
it dies
