Apa potabila trebuie sa aiba temperatura:
Correct Answer
C. 7 - 15°C
Explanation
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.

Daca stratul acvifer se afla la o adancime> 8m, captarea apei se face:
Correct Answer
B. Prin puturi
Explanation
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.

Instalatia care curata apa adunata de reteaua de canalizare se numeste:
Correct Answer
B. Statie de epurare a apei

The correct answer is "statie de epurare a apei" because it refers to the installation that cleans the water collected from the sewer system. "Statie de tratare a apei" would mean water treatment station, which is a more general term and may not specifically refer to the cleaning of water from the sewer system. "Statie de transmisie" means transmission station, which is unrelated to water cleaning. "Statie de pompare" means pumping station, which is also unrelated to water cleaning.
