Answer the following question given this paragraph: Summary A measure of the disorder of a system is its entropy (S), a state function whose value increases with an increase in the number of available microstates. Areversible process is one for which all intermediate states between extremes are equilibrium states; it can change direction at any time. In contrast, anirreversible process occurs in one direction only. The change in entropy of the system or the surroundings is the quantity of heat transferred divided by the temperature. The second law of thermodynamics states that in a reversible process, the entropy of the universe is constant, whereas in an irreversible process, such as the transfer of heat from a hot object to a cold object, the entropy of the universe increases. Q: A measure of the disorder of a system is called its what? Choices: - lose - spectral - function - entropy A:
(Answer)
entropy
Ques: Answer the following question given this paragraph: In convection, materials move depending on their heat relative to nearby materials. Q: The process in which materials move depending on their heat relative to nearby materials is known as what? Choices: - induction - radiation - ventilation - convection A:
Ans: convection
(Q).
Answer the following question given this paragraph: An esterification is a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid. Esterification is a subcategory of condensation reactions because a water molecule is produced in the reaction. The reaction is catalyzed by a strong acid, usually sulfuric acid. When the carboxylic acid butanoic acid is heated with an excess of methanol and a few drops of sulfuric acid, the ester methyl butanoate is produced. Methyl butanoate has the scent of pineapples. The reaction is shown below with both molecular and structural formulas. Q: What do you call a condensation reaction in which an ester is formed from an alcohol and a carboxylic acid? Choices: - transesterification - esterisation - decarboxylation - esterification A:
(A).
esterification
Ques:Answer the following question given this paragraph: Exocytosis is the type of vesicle transport that moves a substance out of the cell. A vesicle containing the substance moves through the cytoplasm to the cell membrane. Then, the vesicle membrane fuses with the cell membrane, and the substance is released outside the cell. You can watch an animation of exocytosis at the link below. Q: The type of vesicle transport that moves a substance out of the cell is called? Choices: - morphogenesis - metabolism - endocytosis - exocytosis A:

Ans:exocytosis
Ques:Answer the following question given this paragraph: Earthquakes can cause tsunamis . These deadly ocean waves may result from any shock to ocean water. A shock could be a meteorite impact, landslide, or a nuclear explosion. But most come from large underwater earthquakes. Q: By shocking ocean water, earthquakes can cause what deadly ocean waves? Choices: - deep currents - ebb tides - typhoons - tsunamis A:

Ans:
tsunamis
