Because the temperature causes it to go the physical change like if water is froze the temperate just caused it to go through another state of matter another example as if the ice got melted you would need high temperature to cause this change physically. Let me know if I help or if their is anything I can change for you to understand better
False. A sound wave is an example of a mechanical wave, not an EM wave.
Hope this helps! :)
Covalent bonding is a type of chemical bonding wherein there is a sharing of electrons to achieve chemical stability or the octet rule. For instance, the chlorine atom with one unpaired electron shares an electron to sodium to become stable. In the given examples, the situation that portrays covalent bonding is when Chlorine accepts 1 electron from calcium to form a stable bond.
Answer:Increase in the entropy of the universe are the result of chemical reactions
Explanation:
The second law tells about the quality of energy such that any isolated system tends to become more disordered. Any natural Process occurring on its own is irreversible and entropy is increasing for that process.
The entropy of the Universe is increasing which is the result of chemical reactions. Any chemical reaction which increases the number of gas molecules will generate more entropy. Entropy in simple meaning is the order of randomness.
The answer is c, but I'm not sure, just so you know
