104. An air-water vapour mixture has a dry-bulb temperature of 333 K and a dew-point temperature of 313 K. The total pressure is 101.3 kPa and the vapour pressure of water at 313 K is 7.3 kPa and that at 333 K is 19.91 kPa. The humidity of air expressed as kg of water vapour per kg of dry air is (a) 0.048 (b) 0.079 (c) 0.122 (d) 0.152

The adiabatic process uses specific numbers, or rates, to
decrease a parcel’s temperature and dew point temperature. Those
rates are:
- Unsaturated air will decrease by 10 deg C for every 1
kilometer (km) of lift. This is called the dry adiabatic lapse
rate.
- Saturated air will decrease by 6 deg C for every km of lift.
This is called the moist adiabatic lapse rate.
- The parcel’s dew point temperature will decrease by 2 deg C
