Answer is: this is chemical <span>type of CBRNE exposure.
</span>CBRNE is an acronym for Chemical, Biological, Radiological, Nuclear and high yield Explosives (usually used for weapons of mass destruction).
Chemical weapons can be: nerve agents, blister agents, choking agents and blood agents.
Erosion. The waves breaking on the cave and washing up on it will eventually start breaking down the rocks
20.21*10^-4 mg/L is the concentration.
Explanation:
Given:
Pressure=1 atm.
Temperature= 0 degrees
Volume percent of air is 21%
Henry's Law constant K = 2.28 x 10^-3 mole/L-atm
The partial pressure of oxygen is 0.21 atm.
By Henry's law:
Concentration= K X Partial pressure
= 2.28*10^-3 *0.21
= 4.79*10^-4 moles/litre
Since, at STP 1 mole of oxygen occupies volume of 22.4L
concentration =mass/volume
mass = 4.79*10^-4-4*22.4
= 20.21*10^-4 mg
20.21*10^-4 mg/L is the concentration.

Answer:
Freeze wedging is caused by the repeated freeze-thaw. Frost wedging occurs as the result of 9% expansion of water when it is converted to ice. Cracks filled with water are forced further apart when it freezes.
