Primary Pollutant:
1. They are pollutants which are passed into environment in the form they are produced.
2. They belong to various categories like particulate, aerosol, reduced, oxidized.
3. They are less toxic.
4. They do not show synergism.
5. Primary pollutants persist in the form they are released in the environment.
Secondary Pollutants
Some of the major differences between primary and secondary pollutants are as follows:

2. They belong to various categories like particulate, aerosol, reduced, oxidized.
3. They are less toxic.
4. They do not show synergism.
5. Primary pollutants persist in the form they are released in the environment.
Secondary Pollutants:
1. The pollutants develop as a result of interaction of primary pollutants and environmental constituents.
2. They are generally oxidizing.
3. They are more toxic.
4. Secondary pollutants show synergism.
5. They are modified products

Student X hears the alarm first because sound travels faster in solids than in gases.
<h3>Speed of sound</h3>
Sound is a wave, as such, sound waves are able to travel across long distances. The speed of sound is greatest in solids since the gases have a high density owing to the fact that the molecules are closely packed.
Now, we can infer from this that student X hears the alarm first because sound travels faster in solids than in gases.
