Answer:

5.12

Explanation:

5.22 x 10 - 3 = [?] x 10 - 2 (move - 2 to the other side with changed sign)

5.22 x 10 - 3 + 2 = [?] x 10 (divide both sides by 10)

[?] = (5.22 x 10 - 1) / 10

[?] = 5.12

Mrs. Borunda has a sample of oxygen gas that occupies a volume of 600 L at 400 atm pressure. What will the pressure be if she in

kotykmax [81]

Answer:

P₂ = 300 atm

Explanation:

Given that,

Initial volume, V₁ = 600 L

Initial pressure, P₁ = 400 atm

We need to find the pressure if the volume is 800 L.

We know that the relation between pressure and volume is given by :

$P\propto \dfrac{1}{V}\\\\\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{600\times 400}{800}\\\\P_2=300\ atm$

So, the new pressure is equal to 300 atm.

Which process releases energy that eventually produces lightning in the thunderstorm?

Ira Lisetskai [31]

Answer:

Answer: B. Water condenses to form clouds.

Explanation:

When the moisture condenses, this results in the release of energy. The energy causes the air to be warm and results in the rise of air in the upper atmosphere. This process results in the instability in the atmosphere and cumulonimbus clouds are formed. These clouds support lightening during a thunderstorm.
