Answer:
when you boil water, you convert it into water vapor, which leaves the pot and mixes with the atmosphere. If you boil the pot long enough, eventually all the water in it is converted to vapor and leaves. the pot is then empty.
Explanation:
Answer:
Because of statements (a), (c) and (d).
Explanation:
Let's evaluate each statement to know why they focus on higher alcohols instead of ethanol:
(a) It is easier to produce higher alcohols in microbes than it is to produce ethanol<u>.</u> This is true<u> since ethanol is the major biofuel in the world because it can be easily produced by fermentation technology developed a long time ago. Recently, higher alcohols are produced from microorganisms that are used as microbial cell factories.</u>
(b) Higher alcohols have a higher hygroscopicity than ethanol. This is false since ethanol is more hygroscopic than higher alcohols.
(c) Higher alcohols have a lower vapor pressure than ethanol. This is true, ethanol has a higher vapor pressure than higher alcohols. The vapor pressure is important since it can affect the proper cold starting of the engine.
(d) Higher alcohols have a higher energy density than ethanol. This is true since the production of higher alcohols as biofuels is more desirable than the ethanol because higher alcohols have a high energy density and other more advantages than the use of ethanol.
Therefore the answer of why did they focus on higher alcohols to add to or substitute gasoline instead of ethanol is because of the statements (a), (c) and (d).

Answer:
La Nina
Explanation:
La Nina -
The word La Nina means " the little girl " , in spanish language .
La Nina , is an ocean - atmospheric process , which occurs in the eastern equatorial Pacific Ocean .
It is exactly opposite of El Nino , which means " the little boy " .
In the phase of La Nina , the temperature of the eastern equatorial Pacific Ocean becomes lower than the usual temperature by around 3°C to 5°C .
This phase of La Nina is for around 5 months in an year .
Hence , from the given statement of the question ,
The correct term is La Nina .
