Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.

Answer:
The volume is
<h2>180 mL</h2>
Explanation:
In order to solve for the volume we use the formula for Boyle's law which is
<h3>
</h3>
where
P1 is the initial pressure
V1 is the initial volume
P2 is the final pressure
V2 is the final volume
Since we are finding the final volume we are finding V2
Making V2 the subject we have
<h3>
</h3>
From the question
P1 = 300 mmHg
V1 = 300 mL
P2 = 500 mmHg
Substitute the values into the above formula and solve for the final volume obtained
That's
<h3>
</h3>
We have the final answer as
<h3>180 mL</h3>
Hope this helps you
