- D.
Reziduul fix
Correct Answer
A. Duritatea apeiExplanation
The correct answer is "duritatea apei" (water hardness). The content of Ca (calcium) and Mg (magnesium) in water determines its hardness. Hard water contains high levels of these minerals, which can cause scaling and reduce the effectiveness of soaps and detergents.Rate this question:

Apa potabila trebuie sa aiba temperatura:
- A.
5 - 20°C
- B.
7 - 25°C
- C.
7 - 15°C
- D.
5 - 25°C
Correct Answer
C. 7 - 15°CExplanation
The correct answer is 7 - 15°C. This range of temperature is ideal for drinking water because it is cool enough to be refreshing but not too cold to cause discomfort. Water that is too cold may be difficult to drink and can also shock the system. On the other hand, water that is too warm may not be as refreshing and can promote the growth of bacteria. Therefore, maintaining a temperature between 7 - 15°C ensures that the water is both enjoyable and safe to drink.Rate this question:

Daca stratul acvifer se afla la o adancime> 8m, captarea apei se face:
- A.
Prin drenuri orizontale
- B.
Prin puturi
- C.
Nu este economic
Correct Answer
B. Prin puturiExplanation
If the water table is located at a depth of more than 8m, the most suitable method for extracting water is through wells. This is because wells are vertical shafts that can reach greater depths compared to horizontal drains. Using horizontal drains would not be effective in this case as they are typically used for shallow water tables. Additionally, the option of it not being economical is not applicable here as the question is asking for the method of water extraction, not the cost-effectiveness of the process.Rate this question:
