Determine which of these elements would be liquid at 525 K (assume samples are protected from air): A. platinum, Pt B. selenium, Se C. bismuth, Bi D. copper, Cu E. calcium, Ca

Answers

Answer:

selenium, Se

Explanation:

Selenium is the only element that has a melting point below 525 K. Therefore, it would be the only element that would be liquid at that temperature.

Final answer:

At 525 K, only bismuth would be in the liquid phase as its melting point is 544.7 K and boiling point is 1837 K, while all other elements would be in the solid state.

Explanation:

The question asks about the phase of different elements at a specific temperature of 525 K. To answer the question, we need to know the melting and boiling points of these elements: platinum (Pt), selenium (Se), bismuth (Bi), copper (Cu), and calcium (Ca).

At 525 K, bismuth (Bi) would be in the liquid state as its melting point is 544.7 K and boiling point is 1837 K. All other elements mentioned have melting points and boiling points higher than 525 K, so they would be in the solid state.

What would be the result if Earth's unique atmosphere did not exist?

Answers

Then the earth would most likely not be able to support life. Our earth would be similar to mars. In that it might have supported life. It the thin atmosphere would over all be unable to sustain more complex species. The earth would also be much colder because the green house effect is what maintains our relatively warm atmosphere.
