Key to understanding scuba diving is the concept of pressure, and how it varies with depth. We intuitively understand that pressure is some type of force, but how is it actually defined? Pressure is a force or weight<span> per unit area. All matter, </span>including air<span>, has weight due to earth's gravity. Accordingly, anything exposed to air is under pressure - the weight of the atmosphere above it. This weight of air, due to gravity, is known as </span>atmospheric pressure<span> </span>

A gas has a volume of 45.0 mL and a pressure of .98 atm. If the pressure increased to 2.1 atm and the temperature remained the s
goblinko [34]

Answer: The new volume is 95.45 mL.

Explanation:

Given: V_{1} = 45.0 mL,         P_{1} = 0.98 atm

P_{2} = 2.1 atm,               V_{2} = ?

According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.

Therefore, formula used to calculate the new volume is as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}

Substitute the values into above formula as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}\\\frac{0.98 atm}{45.0 mL} = \frac{2.1 atm}{V_{2}}\\V_{2} = 95.45 mL

Thus, we can conclude that the new volume is 95.45 mL.

qwelly [4]

Answer:

Polycyclic aromatic hydrocarbons (from petroleum)

Explanation:

Polycyclic aromatic hydrocarbons (PAH) is a group of compounds which contain more than one aromatic ring. Typically examples include; naphthalene, anthracene, phenanthrene etc.

PAH are present in petroleum products. Almost everyone is regularly exposed to vehicles or other equipments that uses petroleum products as fuel. PAH is usually released from the combustion engine of these equipments and may be inhaled by humans. Thus there is a very high risk of PAH exposure compared to other items listed in the question.

PAHs are known to cause different kinds of cancer and other types of health issues in the body. The most disturbing toxicity of PAH is its carcinogenicity which makes it a very serious potential health risk for humans exposed to it on regular basis.
