Ask 3 questions that will help you better understand the coronavirus
lord [1]

1: China is agreeably a third world country because they do not know what they should eat, they think that beating an animal and causing it pain and suffering makes the meat taste better which is very, very unjust and cruel. This disease was started where a Bio-Disease plant was, and considering coronavirus is spreading so fast and killing so many people, ( not unlike the swine flu that ALSO originated in China ) This indicates it is very possible that this disease could have been engineered. ( not unlike the swine flu either )

2: The person itself is smart, people are stupid, fearmongering, and have been weakened through the years. The moment the media said there was a pandemic, everyone ran to the nearest convenience store to buy toilet paper, then they locked themselves in their houses because people said to do so, they bought surgical masks ( that only help you if you have secondary breathing problems, because you go to take them off and touch your face ) that they HEARD will help them. MY opinion is do what makes YOU feel comfortable, you can't help other people, but you can help yourself.

3: I don't exactly understand this question, so if you could rewrite this part I could give you an answer.

Hope this helps, if not, comment below please!!!

What happens to the temperature of a substance during a phase change? Why does this happen?
natima [27]

Answer:What happens to the temperature of a substance during a phase change? Why does this happen?

Explanation:During a phase change the temperature remains constant. This is because the heat supplied to change the state of matter is used in breaking the intermolecular forces and other attractive forces. Therefore, the temperature remains constant as no heat is absorbed or released.

17. An industrially important element contains
likoan [24]

Answer:

Iron (Fe)

Explanation:

The number of electrons (-) is usually the same as the number of protons (+) in the atom of the element (unless it is an ion).

The element described has 26 electrons, so we can assume that it has 26 protons as well. The number of protons in an atom is the atomic number of element that the atom is.

Element 26 on the PTE is Iron (Fe), which does rust (oxidation) in air and water.
