.If we add one spoon of sugar and one spoon of yeast in half glass of lukewarm water and leave it undisturbed for 10 minutes. Which of the among following changes cannot be seen?
Answers
Answer:
On stirring, temperature increases
C
Stirring increases the rate of interaction
Stirring, or agitation helps to disperse the particles of sugar throughout the water, which is another way of increasing the surface area of the sugar and accelerating the time it takes to dissolve. The stirring motion also increases kinetic energy, which increases the temperature of the solution – and that's the next way to make the sugar dissolve more quickly. An increase in the kinetic energy of the constituent particle increases the rate of interaction as well as the temperature of the solution.
how it helps
As your question is incomplete, the correct question is :-
If we add one spoon of sugar and one spoon of yeast in half glass of lukewarm water and leave it undisturbed for 10 minutes. Which of the among following changes cannot be seen?
A. bubbles will be formed
B. rise in temperature
C. release of carbon dioxide gas
D. change in colour
The correct answer of this question is D that Change in colour cannot be seen.
When we add one spoon of sugar and yeast in half glass of lukewarm water and leave it undisturbed for 10 minutes, we see that following reaction will take place.
C₆H₁₂O₆ ⇒ C₂H₅OH + CO₂ in presence of yeast as a catalyst in this reaction.
During this reaction, C₆H₁₂O₆ , which is Glucose reacts with yeast under the influence of lukewarm water, it releases Ethanol (C₂H₅OH) and Carbin Dioxide( CO₂ ) as by products. Due to the release of ethanol, the temperature of the solution rises up and a process called Fermentation took place.
What is fermentation?
The breaking down of glucose particles into alcohol and carbon dioxde is called Fermentation.
