Difference Between Fog and Smog: In the winter season, you must have seen in the morning that there is a slight haze in the atmosphere, due to which you cannot see the distance clearly. The visibility in the environment reduces drastically and after a few meters the visibility becomes hazy. Sometimes this situation happens due to fog and sometimes this situation happens due to pollution. In fact, due to high AQI, haziness starts appearing in the atmosphere and like fog, there is smoke everywhere. In such a situation, the question is how to know whether the smog in your city is fog or pollution. Let us explain to you the difference between them today.
What is fog? (Fog)
Fog is a type of water vapor. Air can hold a certain amount of water or water vapor in gaseous state. As the amount of water in the air increases, the air becomes more moist. When the water vapor starts saturating the air completely, the water droplets start to condense, or rather, turn from gas back to liquid. Then these droplets remain in the air and appear as a layer of thick mist, which is known in common language as fog.
Fog forms when there is a difference of less than 2.5 °C between the air temperature and the dew point. Seeing the fog can be identified in such a way that if there is fog in the atmosphere then it looks like a white sheet and does not reach much height. It only contains water vapor and you feel cold.
What is haze or smog? (Smog)
Smog is formed when fog mixes with smoke. Smog is formed by a combination of fog and smoke ie fog and smoke. It contains dangerous and deadly gases like benzene and sulphur. Dioxide etc. are found in large quantities. These gases together form smoke first and then fog. By reacting, chemical compounds are formed, due to which smog is formed. Most of these smog-producing compounds come from factories, smoke from burning crops and stubble, and many power plants where these dangerous gases are used regularly.
It is made up of pollution and fog and it becomes more dangerous when the temperature is low. The temperature is low even in winter, so it is often formed in this season. Smog can cause irritation in the eyes, cough, shortness of breath, obstruction in the lungs and many other respiratory diseases. A different kind of smell is felt in smog and due to the presence of pollution particles in it, its color is also like gray. Visibility is greatly reduced in this.
How to differentiate between the two?
Difference between fog and smog can be known by looking at it. Actually, in the condition of smog, there is slight blackness in the air, that is, smog is of gray colour. But, when there is only fog, then you see a layer of white color, not gray color in the atmosphere. It is said for fog that it does not reach much height, while smog floats in the air and acts as a gas chamber. In case of smog, you find it difficult to breathe and within a short time you have to face problems like sore throat. This does not happen in case of fog, you just feel more cold.
