Answer:
23 kPa = Partial pressure O₂
Explanation:
In a mixture of gases, the sum of partial pressure of each gas that contains the mixture = Total pressure
Total pressure = Partial pressure N₂ + Partial pressure CO₂ + Partial pressure O₂
95 kPa = 48 kPa + 24 kPa + Partial pressure O₂
95 kPa - 48 kPa - 24 kPa = Partial pressure O₂
23 kPa = Partial pressure O₂
Answer:
The White Dwarfs are very hot stars, which are small in size and relatively dim. They are found in the lower left of the H-R Diagram. The Main Sequence is a band of stars, which includes most of the stars, like our Sun. These are usually smaller stars, often dwarf stars.
