Answer:
the standard unit of radiation related to biological hazards is known as the Roentgen.
Explanation:
Answer:
the answer is A
Explanation:
since during a cold front the cold air replaces the warm air
What happens when carbon dioxide builds up in your lungs?
If the person's breathing passage were filled with carbon dioxide instead of air, it would lead to respiratory failure.
Signs of respiratory failure:
- The symptoms of respiratory failure depend on the cause and the levels of oxygen and carbon dioxide in your blood.
- The inability to breathe in enough air and shortness of breath are both signs of low blood oxygen levels. Your fingernails, skin, and lips could all be blue in hue.
- Rapid breathing and confusion can occur when there is a high carbon dioxide level.
- Those who experience respiratory failure can lose consciousness or become extremely tired. Arrhythmia (irregular heartbeat) may also exist in them. If your brain and heart aren't getting enough oxygen, you can experience these symptoms.

<em><u>Explanation For The Three States OF Matter On the Basis OF Characteristics Of Particles / Molecules OF Matter.</u></em>

<em><u>In solids the molecules are closely packed . There is a strong force of attraction between the molecules and the space between them is very small (almost negligible). The molecules are , therefore, not free to move . They merely vibrate their mean positions . This makes solids hard and difficult to compress , giving them a fixed shape and size.</u></em>

<em><u>In the case of liquids , the molecules are not closely packed. They do not attract each other as strongly as the molecules of solids. Thus, the intermolecular spaces are larger and the molecules are able to move about more freely . This makes liquid flow and take the shape of the container into which it is poured. Thus, liquids have a fixed volume but no def</u></em><em><u>i</u></em><em><u>nite shape of their own .</u></em>
<h3><em><u>G</u></em><em><u>a</u></em><em><u>s</u></em><em><u> </u></em><em><u>:</u></em><em><u> </u></em></h3>
<em><u>In the case of gases, the molecules hardly attract each other. They lie far a part from each other and the intermolecular spaces are, therefore, very large. . The intermolecular force of attraction is so weak that the molecules have great freedom of movement . As a result , gases have neither a fixed shapenor a fixed volume . They completely full up spacw available to them. They can be easily compressed as well, thus decreasing the gaps between their molecules .</u></em>

Answer:
The pressure at 179 K is 21.8 kiloPascal.
Explanation:
To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial pressure and temperature of the nitrogen gas.
are the final pressure and temperature of the nitrogen gas.
We are given:
Putting values in above equation, we get:
The pressure at 179 K is 21.8 kiloPascal.
