Answer: The Relative humidity is 50%
Explanation: Relative humidity is the ratio of the air’s water vapour content (the actual amount of water vapour in the air) to its water vapour capacity at a given temperature. It depends on temperature and the pressure of the system of interest and it is usually expressed in PERCENTAGE; the higher the percentage, the more humid the air/water mixture.
The formula of Relative humidity (%) = (water vapor content / water vapor capacity) x 100%
Where: Water vapour content is the actual amount of water vapour in the air. Which is 10g/cm³ from the question above;
Water vapour capacity is the air's capacity to hold water vapour. Which is 20g/cm³ from the question above.
Therefore, RH(%)= (10g/cm³ / 20g/cm³) x 100 = 0.5 x 100= 50%
This means that the air contains half of the water vapour it could hold at 20 degree Celsius.
The biosphere is made up of all living things (organisms).
The biosphere includes animals, biomes, population, communities, and ecosystems. The biomes are climate regions which can contain certain types of animals and plants. An ecosystem is all living things in one specific area, also such as plants, animals, and organisms.
