Absolute humidity in atmosphere at $ 10^\circ $ is $5.0$ g/m$^3$ and maximum amount of water air can hold at same temperature is $ 10$ g m$^3$. What will be the relative humidity at the same temperature?
Understanding Relative Humidity
Relative humidity (RH) indicates the amount of water vapor present in the air compared to the maximum amount the air could hold at a specific temperature. It's expressed as a percentage.
Humidity Calculation Formula
The formula to calculate relative humidity is:
$ \text{Relative Humidity (RH)} = \frac{\text{Absolute Humidity (AH)}}{\text{Saturation Humidity (SH)}} \times 100\% $
Applying the Formula
Given values:
- Absolute Humidity ($AH$) = $5.0$ g/m$^3$
- Saturation Humidity ($SH$) = $10$ g/m$^3$
Substitute these values into the formula:
$ \text{RH} = \frac{5.0 \text{ g/m}^3}{10 \text{ g/m}^3} \times 100\% $
Result
Performing the calculation:
$ \text{RH} = 0.5 \times 100\% $
$ \text{RH} = 50\% $
Therefore, the relative humidity at $10^\circ$ C is $50\%$.
Important Questions from Atmosphere

I. They look like cotton wool.
II. They exist in patches and have flat base.
III. They are generally formed at a height of 4 to 7 km.Given below are two statements :
Statement (I): Atmospheric stability is important because it determines the ability of pollutants to disperse vertically in the atmosphere.
Statement (II): In summer season in India. the atmosphere is generally stable.
In the light of the above statements, choose the correct answer from the options given
