It looks correct to me. Good job
Answer:
The following might explain the lack of cloud formation
- The air package never reaches its dew point.
- There are too few aerosols present in the air package.
<u>Explanation</u>:
For the formation of the cloud the air in the higher position should have much colder than that of the surface. The vapours travels till it reaches the point where it has lower temperature as well as the pressure so that the water will condense into the droplets which will result in the formation of the cloud. When those vapours condenses to the liquid or to the solid it will release some of it energy to the air. For the formation of the cloud three things are mandatory and they are moisture, cooling air and the condensation nuclei. Also, for the formation of clouds, suspended particles like aerosols are required for the water to condense. As there are few aerosols, water doesn't get to condense.
Answer:
The catalyst would be the tablets.
Explanation:
The tablets start the reaction. That is what catalysts do.
An air-purifying respirator that employs a blower to pump air through filters or cartridges and into the user's breathing zone is known as a powered air-purifying respirator, or PAPR. In comparison to a powered or negative-pressure half mask, this generates a positive pressure inside the facepiece or hood, increasing protection.
<h3>What kind of respirator offers a separate source of clean air?</h3>
For entry into or exit from settings regarded as IDLH, Self-Contained Breathing Apparatus (SCBAs) are employed. They can be either open circuit or closed circuit and contain their own breathing air supply.
<h3>What 2 categories of respirators exist?</h3>
Air-purifying and supplied-air respirators are the two main categories of respirators. Respirators that purify the air remove airborne pollutants such particles, dangerous vapors, and/or gases. They are suitable for use in surroundings with low levels of pollution and in areas with enough oxygen.
<h3>When should you use an air purifying respirator?</h3>
a small, unproven area. a lack of oxygen in the atmosphere. Firefighting. Contaminants with a lower explosive limit (LEL—the concentration at which a gas or vapour could ignite) of at least 20%
