1. A mixture of dry air and water vapour, when the air has diffused the maximum amount of water vapour into it, is called
- Dry air
- Moist air
- Saturated air
- Specific humidity
2. The temperature of air recorded by a thermometer, when it is not effected by the moisture present in it, is called
- Wet bulb temperature
- Dry bulb temperature
- Dew point temperature
- None of these
3. For unsaturated air, the dew point temperature is ........... wet bulb temperature.
- Equal to
- Less than
- More than
4. The difference between dry bulb temperature and wet bulb temperature, is called
- Dry bulb depression
- Wet bulb depression
- Dew point depression
- Degree of saturation
5. During sensible cooling of air, the specific humidity
- Increases
- Decreases
- Remains constant
6. During sensible cooling of air, the dry bulb temperature
- Increases
- Decreases
- Remains constant
7. During sensible cooling of air, the wet bulb temperature
- Increases
- Decreases
- Remains constant
8. The process generally used in winter air conditioning to warm and humidify the air, is called
- Humidification
- Dehumidification
- Heating and humidification
- Cooling and dehumidification
