Why does a star expand into a red giant?​

Chemistry
1 answer:
devlian [24]3 years ago
7 0

Answer:

"Hydrogen is still available outside the core, so hydrogen fusion continues in a shell surrounding the core. The increasingly hot core also pushes the outer layers of the star outward, causing them to expand and cool, transforming the star into a red giant."

At what point will potential energy be the highest? The object has a mass of 5 kg
Sloan [31]

Explanation:

Given that,

The mass of the object, m = 5 kg

We need to find the maximum potential energy. When the height of the object is maximum it will have the maximum potential energy.

The attached figure shows that the maximum height is 25 m. The formula for the potential energy is given by :

P=mgh\\\\P=5\times 9.8\times 25\\\\P=1225\ J

So, when the height is 25 m, the object will have the highest potential energy.

As the [H+] in a solution decreases, what happens to the [OH–]? A. It increases and the pH increases. B. It increases and the pH
AleksAgata [21]
<h3><u>Answer;</u></h3>

D. It decreases and the pH increases.

<h3><u>Explanation;</u></h3>
  • pH is a measure of the hydorgen ion concentration of a solution. Solutions with a high concentration of hydrogen ions have a low pH and solutions with a low concentrations of H+ ions have a high pH.
  • <em><u>[H+] and [OH-] are inversely related. Therefore; As the concentration of H+ increases the pH decreases. Since the concentrations of H+ and OH- are inversely proportional, as one goes up, the other goes down. </u></em>
  • <em><u>Therefore, an increase in OH- concentration will correspond to an increase in pH and a decrease in the concentration of H+.</u></em>
