there are 8 moon phases.
They are - First quarter, waxing crescent, new, waning crescent, third quarter, Waning gibbous, full, and waxing gibbous
Given the data from the question, the final temperature is 200 K, while pressure remains constant.
<h3>Basic concepts </h3>
To obtain the correct answer to the question, we shall consider two conditions:
- Case 1 (temperature is constant)
- Case 2 (pressure is constant)
<h3>Case 1 (Temperature is constant) </h3>
We shall determine the new pressure by using the combined gas equation (P₁V₁ / T₁ = P₂V₂ / T₂) as illustrated below:
- Initial volume (V₁) = 3 L
- Initial pressure (P₁) = 1 atm
- Temperature = constant
- New Volume (V₂) = 2 L
- New pressure (P₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
Since temperature is constant, we have:
P₁V₁ = P₂V₂
3 × 1 = P₂ × 2
3 = P₂ × 2
Divide both side by 2
P₂ = 3 / 2
P₂ = 1.5 atm
<h3>Case 2 ( pressure is constant) </h3>
We shall determine the new temperature by using the combined gas equation (P₁V₁ / T₁ = P₂V₂ / T₂) as illustrated below:
- Initial volume (V₁) = 3 L
- Initial pressure (T₁) = 300 K
- Pressure = constant
- New Volume (V₂) = 2 L
- New pressure (T₂) =?
P₁V₁ / T₁ = P₂V₂ / T₂
Since pressure is constant, we have:
V₁ / T₁ = V₂ / T₂
3 / 300 = 2 / T₂
1 / 100 = 2 / T₂
Cross multiply
T₂ = 100 × 2
T₂ = 200 K
SUMMARY
- when the temperature is constant, the new pressure is 1.5 atm
- When the pressure is constant, the new temperature is 200 K
From the calculations made above, we can conclude that the correct answer is:
The final temperature is 200 K, while pressure remains constant.

for what I can see in the picture the volume is 155
Explanation:
Answer:
Due to the iron inside the earth.
Explanation:
Imagine a sphere of Iron, as big as two-third the size of the moon and as hot as 5700 Kelvin. That is the Earth’s core.
The iron core isn't in its liquid form even at that temperature because it is crushed under immense gravity. This core is surrounded by 2000 km of other metals like iron and nickel which are in their molten state.
The temperature is not the same at every point in this molten layer. The hotter and less dense matter rises up, and the warm denser matter sinks. This causes convectional currents in the interior of the Earth.
Because of the Earth’s spin, there is a force that is established called the Coriolis force which causes swirling whirlpools here too.
This flow of molten metals produces electric currents which generate self-sustaining magnetic fields. And as a result of the Coriolis force, all these combined effects add up to produce one big magnetic field engulfing the Earth aligned in one direction.
