Answer:
Partial pressure
Explanation:
the scientists is measuring different pressure, so it would be partial pressure. Hope that this helps you and have a great day :)
The <span>modern-day quantum model of the atom known as the wave mechanical model depicts that the </span>electron was a three dimensional wave circling the nucleus in a whole number of
wavelengths allowing the waveform to repeat itself as a stable standing wave
(it can absorb energy form a nearby source which is oscillating at a proper
frequency) representing the energy levels of Bohr model.
