The image below shows what scientific process? 1. oxidation 2. landslide 3. alluvial fan 4. frost wedging

4. Frost wedging  

Step-by-step explanation:

Water expands about 9 % as it freezes.

Thus, water in cracks forces them apart when it freezes.

When the ice thaws and freezes again, the crack is forced further apart.

The rock may eventually split into pieces.

The repeated freeze-thaw cycle is called freeze wedging.

1. is wrong. Oxidation is the chemical reaction of a substance with oxygen . The splitting of a rock is a physical change.

2. is wrong. A landslide is the movement of ground down a slope.

3. is wrong. An alluvial fan is a triangle-shaped mass of sediment that a river deposits when its flow is suddenly slowed.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
