When a cold can of soda is insulated, the heat flow into the can on a hot day ____.a. increases
c. stays the same
b. decreases
d. both b and c

Answers

Answer:

Option C, stays the same

Explanation:

Heat flow by vibrating the molecules in any medium. Therefore, some medium is essential for heat transfer and hence no heat flows across an insulated vacuum can. Without any medium, heat transfer is stopped which means that neither the heat from outside environment can flow into the can nor it can flow from the can into the external environment.  

Hence, the heat contained within the can shall remain the same.  

Thus, option C is correct
The word insulate means to protect from heat, cold,...
So when a can is insulated, means that is protected from heat.
So the answer is:
C. stays the same :)))

During which process is ethanol produced?A-lactic acid fermentation
B-alcohol fermentation
C-citric acid cycle
D-electron transport chain

Answers

Answer:

The correct answer would be B-alcohol fermentation.

Alcohol fermentation or ethanol fermentation is a type of anaerobic respiration by which organism (such as yeast) convert sugar such as glucose, sucrose et cetera into ethanol and carbon dioxide in order to produce energy.

First, glucose is converted into 2 molecules of pyruvate by the process of glycolysis. It leads to the formation of 2 molecules of ATP (adenosine triphosphate) and 2 molecules of NADH.

Then, two molecules of pyruvate are converted into two molecules of acetaldehyde with the help of enzyme pyruvate decarboxylase. Two molecules of carbon dioxide are released as a byproduct.

Lastly, two molecules of acetaldehyde are converted into two molecules of ethanol with the help of enzyme alcohol dehydrogenase. It consumes two NADH and regenerates two NAD⁺ lost during the process of glycolysis.

Hence, the net gain of alcohol fermentation is two ATP.

Thus, we can say that ethanol is produced during alcohol fermentation.

During alcohol fermentation ethanol is produced.

Alcohol fermentation involves the break down of sugars in organisms such as yeast to form ethanol or alcohol, carbon dioxide and release energy.

Further Explanation;

Anaerobic respiration

  • Anaerobic respiration on the other hand is a type of respiration that occurs in absence of oxygen gas.
  • It involves the breakdown of organic compounds to form small amount of energy in the form of ATP and ethanol or lactic acid as byproducts.

Alcohol fermentation

  • Alcohol fermentation is a type of anaerobic respiration where an alcohol is formed as a byproduct.
  • During alcohol fermentation organism such as yeast convert sugars such as glucose, sucrose into ethanol and carbon dioxide in order to produce energy.

Stages of Alcohol Fermentation

Glycolysis;

  • One glucose molecule is broken down to pyruvate and two molecules of ATP are formed. This leads to generation of two molecules of ATP and two molecules of an energy carrier NADH.

Fermentation;

  • Pyruvate from glycolysis is converted to ethanol.
  • This occurs in two steps

Step 1

  • Pyruvate is first converted into two molecules of acetaldehyde, which is catalyzed by the enzyme pyruvate dehydrogenase and two molecules of carbon dioxide are released as byproduct.

Step 2

  • Acetaldehyde is then converted into ethanol by the enzyme alcohol degydrogenase which consumes the two molecules of NADH and regenerates NAD+ used during glycolysis.

In which of the following states can water Not exist? A. liquid B. gas C. solid D. none of the above

Answers

Water exists in all the statesofmatter which are the solid, liquid, and gaseous states.

What are the states of water?

Water is known to exist in three different physicalstates. These are the solid state as ice, the liquid state as water itself, and the gaseous state as water vapors.

Under the conditions of standard temperature and pressure, the freezing point of water is zero degrees Celsius. At this temperature, water starts to freeze and attains a solid form which is in the form of ice. The density of ice is lower than the density of water because of the fixed intermolecular distances in ice.

Under the conditions of standard pressure and temperature, water exists in liquid form between temperature ranges of zero to a hundred degrees Celsius. Liquidwater is essential for all organisms. It functions as a universal solvent.

At a temperature above hundred degrees Celsius, the intermolecular integrity between the molecules of water starts to decrease and ultimately breaks completely. In these conditions, the water turns into vapors.

Therefore, water exists in all the states of matter which are solid, liquid, and gaseous states.
