As temperature of this substance rises from 20°c to 50°c, the substance heat and its kinetic energy . a) absorbs; increases b) releases; increases c) absorbs; remains constant d) remains constant; increases

The answer to your question is: letter A

Explanation:

As temperature of this substance rises from 20°C to 50°C, the substance _absorbs___ heat and its kinetic energy __increases___ .

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
