Suppose you place an ice cube into a cup of hot tea? What will happen to the temperature of the ice cube and the tea? A) The tem

perature of the ice will increase quickly, while the temperature of the tea will drop slowly. The liquids may or may not reach equilibrium. B) The temperature of the tea will drop quickly, while the temperature of the ice will increase slowly. The liquids may or may not reach equilibrium. C) The ice will melt and the temperature of the tea will drop quickly; then the change will slow until equilibrium is reached. D) The temperature of the ice will rise slowly at first and the temperature of the tea will drop slowly; then the temperature change quicken until equilibrium is reached.

Sorry this is long, it’s the best I’ve got. The name was chosen based on the time of year (around December) during which these warm waters events tended to occur. The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. The term El Niño refers to the large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific. The vast tropical Pacific Ocean receives more sunlight than any other region on Earth. Much of this sunlight is stored in the ocean in the form of heat. During an El Niño water temperatures in the Pacific Ocean may rise on average 3 - 5 degrees above average

A stream consisting of 48.9 mole% benzene (B) and 51.1% toluene (T) is fed at a constant rate to a process unit that produces tw
marshall27 [118]

The vapor flowrate will vary with time by ;  gradually increasing from zero to one half of the molar feed flow rate and then remain constant ( C )

<u>Although the options related to your question is missing attached below are the missing options </u>

<u />

Vapor flow rate is the amount of vapor per unit of time that flows through a specific area at a given time .

Given that the stream consists of 48.9 mole% of benzene and 51.1% toluene fed at a constant rate into a process unit. The vapor flowrate will vary with time because it will gradually increase from zero to 1/2 of the molar feed flow rate before it will remain constant.  

Hence we can conclude that The vapor flowrate will vary with time by  gradually increasing from zero to one half of the molar feed flow rate and then remain constant.
