Explanation

When the air in a space is heated, its temperature increases. This causes the temperature of the space to increase as well. Therefore, the correct answer is "ΑΥΞΗΘΕΙ Η ΘΕΡΜΟΚΡΑΣΙΑ ΤΟΥ ΧΩΡΟΥ" which translates to "The temperature of the space increases".

Submit
8. ΤΟ ΔΙΑΚΕΝΟ ΣΤΙΣ ΡΑΓΕΣ ΤΟΥ ΣΙΔΗΡΟΔΡΟΜΟΥ ΠΡΟΣΤΑΤΕΥΕΙ ΑΠΟ:

Explanation

The correct answer is "ΤΗ ΣΥΣΤΟΛΗ ΚΑΙ ΤΗ ΔΙΑΣΤΟΛΗ" because the phrase "ΤΗ ΣΥΣΤΟΛΗ ΚΑΙ ΤΗ ΔΙΑΣΤΟΛΗ" translates to "contraction and relaxation" in English. This phrase refers to the process of the heart's contraction and relaxation, which is essential for pumping blood throughout the body. The other options do not accurately describe this process.

Submit
9. Η ΜΕΤΑΤΡΟΠΗ ΕΝΟΣ ΥΓΡΟΥ ΣΕ ΑΕΡΙΟ ΜΟΝΟ ΑΠΟ ΤΗΝ ΕΛΕΥΘΕΡΗ ΕΠΙΦΑΝΕΙΑ ΤΟΥ ΛΕΓΕΤΑΙ:

Explanation

The correct answer is "ΕΞΑΤΜΙΣΗ" (exatmise). This is because the question asks for the process that does not involve a change in temperature. Out of the options given, "ΕΞΑΤΜΙΣΗ" (exatmise) is the only process that does not involve a change in temperature. "ΒΡΑΣΜΟΣ" (vrasmos) is boiling, which involves a change in temperature. "ΣΥΜΠΥΚΝΩΣΗ" (simpiknosi) is condensation, which also involves a change in temperature. Therefore, the correct answer is "ΕΞΑΤΜΙΣΗ" (exatmise).

Submit
10. ΟΤΑΝ ΕΝΑ ΥΓΡΟ ΜΕΤΑΤΡΕΠΕΤΑΙ ΣΕ ΑΕΡΙΟ ΑΠΟ ΟΛΗ ΤΗ ΜΑΖΑ ΤΟΥ ΕΧΟΥΜΕ:

Explanation

The correct answer is "ΒΡΑΣΜΟ" because it is the Greek word for "boiling." The question asks for the process that occurs when water changes from a liquid to a gas, and boiling is the specific term used to describe this process. "ΣΥΜΠΥΚΝΩΣΗ" means condensation, "ΕΞΑΤΜΙΣΗ" means evaporation, and "ΤΙΠΟΤΑ ΑΠΟ ΤΑ ΠΑΡΑΠΑΝΩ" means none of the above.

Submit
11. ΤΑ ΥΓΡΑ ΟΤΑΝ ΨΥΧΟΝΤΑΙ,ΧΑΝΟΥΝ ΕΝΕΡΓΕΙΑ

Explanation

The correct answer is "ΟΛΑ ΤΑ ΠΑΡΑΠΑΝΩ" because all the statements mentioned above are true. The phrase "ΣΥΣΤΕΛΛΟΝΤΑΙ" means "contract," indicating that something is shrinking or reducing. The phrase "ΜΙΚΡΑΙΝΕΙ Ο ΟΓΚΟΣ ΤΟΥΣ" means "their volume decreases," further supporting the idea of contraction. Additionally, the phrase "ΜΕΙΩΝΕΤΑΙ Η ΘΕΡΜΟΚΡΑΣΙΑ ΤΟΥΣ" means "their temperature decreases," which is consistent with the concept of contraction. Therefore, all the statements mentioned above are true.

Submit
12. ΤΟ ΧΕΙΜΩΝΑ ΤΑ ΚΑΛΩΔΙΑ ΤΗΣ ΔΕΗ ΕΙΝΑΙ ΤΕΝΤΩΜΕΝΑ ΕΞΑΙΤΙΑΣ ΤΗΣ....

Explanation

The correct answer is "ΣΥΣΤΟΛΗΣ" because it is the only option that is spelled correctly in Greek. The other options, "ΔΙΑΣΤΟΛΗΣ" and "ΠΗΞΗΣ", have incorrect or missing letters. The last option, "ΟΛΩΝ ΤΩΝ ΠΑΡΑΠΑΝΩ", is not a valid answer as it is a phrase meaning "all of the above" and does not correspond to a single word.

Submit
13. ΤΑ ΒΡΕΓΜΕΝΑ ΡΟΥΧΑ ΣΤΕΓΝΩΝΟΥΝ ΠΙΟ ΕΥΚΟΛΑ ΟΤΑΝ...

Explanation

The correct answer is "ΟΛΑ ΤΑ ΠΑΡΑΠΑΝΩ" because it means "all the above" in Greek. The given statements "ΕΧΕΙ ΗΛΙΟ" (It is sunny), "ΦΥΣΑΕΙ ΑΕΡΑΣ" (It is windy), and "ΕΙΝΑΙ ΑΠΛΩΜΕΝΑ" (They are spread out) are all true based on the given information. Therefore, "ΟΛΑ ΤΑ ΠΑΡΑΠΑΝΩ" is the correct answer as it encompasses all the statements.

The other options, "ΕΞΑΤΜΙΣΗΣ," "ΒΡΑΣΜΟΥ," and "ΤΗΞΗΣ," are related to evaporation, boiling, and melting, respectively. Condensation is the process in which a substance changes from a gas or vapor state to a liquid state, usually due to a decrease in temperature.
