Fog and Smog | BOE Exam

Fog and Smog

Fog :

High-pressure cold-water fogging operates in a fashion similar to other cold-water humidification systems, in that they all generate small water droplets and use heat from
the space to effect evaporation. But fog achieves small particle sizes through the utilization of pressurized water – inherently a more energy-efficient method.

Smog :

Burning coal emits nitrogen oxide along with other organic fuel gases producing unhealthy air pollution called smog. Along with unhealthy air, the chemical mixture in smog produces acid rain, a poison to soil, plants, fish and the people and animals thateat them.
