List - I Indoor climate condition List - II Comfort zone specification (A) Air temperature in $^\circ\text{C}$ (I) 70 (B) Rate of Air movement in m/s (II) 15.6-20.0 (C) Radiant Temperature (III) 0.15 (D) Air humidity in % (IV) 16.7-20.0
Matching Indoor Climate Conditions to Comfort Zones
This question requires matching specific indoor climate parameters from List - I with their corresponding comfort zone specifications in List - II.
Matched Pairs
| List - I: Condition | List - II: Specification |
| (A) Air temperature in $^\circ\text{C}$ | (II) 15.6-20.0 |
| (B) Rate of Air movement in m/s | (III) 0.15 |
| (C) Radiant Temperature | (IV) 16.7-20.0 |
| (D) Air humidity in % | (I) 70 |
Reasoning for Matches:
- Air Temperature (A): A typical comfort zone for air temperature often falls within the range specified in (II) 15.6-20.0 $^\circ\text{C}$, representing cooler conditions suitable for many indoor environments.
- Air Movement (B): For comfort, air movement speed is generally kept low. The value 0.15 m/s (III) is a standard recommended speed within the comfort zone.
- Radiant Temperature (C): Radiant temperature significantly influences perceived comfort and is often closely related to air temperature. The range 16.7-20.0 $^\circ\text{C}$ (IV) aligns well with the specified air temperature range.
- Air Humidity (D): While ideal relative humidity is often cited between 30-60%, 70% (I) can be considered acceptable in certain comfort zone definitions, especially when other parameters are balanced.
Therefore, the correct matching is (A)-(II), (B)-(III), (C)-(IV), (D)-(I).

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
