The characteristic of water that is responsible for frost wedging is that it expands as it freezes and is denoted as option A.
<h3>What is Frost wedging?</h3>
This is referred to a type of physical weathering which is characterized by rocks being broken down into smaller particles through the freezing and thawing process.
This is possible because water is known to expand as it freezes thereby resulting in the expansion of the rocks which forms cracks as a result of frequent freezing and thawing processes.
This is therefore the most appropriate characteristic of water which makes it possible for frost wedging to take place.

When they were full of air, then the Pressure was the Highest 'cause of the larger force under the specified area as compared to when we released it.
We decreased the area of our cheek, so pressure increased and air flows from the cheek (area of high pressure) to the atmosphere (Area of the Lower pressure).
Air flows from Cheek to the Outside of your mouth i.e., in open air.
Hope this helps!
Answer:
P = 5.868 atm
Explanation:
- Pt = (PN2O)(XN2O) + (PO2)(XO2)
assume T = 25°C = 298.15 K
∴ PN2O = 1 atm
∴ XN2O = nN2O/nt
∴ n = PV/RT....ideal gas
⇒ nN2O = ((1atm)(1L))/((0.082atm.L/K.mol)(298.15K)) = 0.041 mol N2O
∴ PO2 = 6 atm
∴ XO2 = nO2/nt
∴ nO2 = ((6atm)(6L))/((0.082atm.L/K.mol)(298.15K)) = 1.472 mol O2
⇒ nt = nN2O + nO2 = 0.041 + 1.472 = 1.513 mol
⇒ XN2O = 0.041/1.513 = 0.03
⇒ XO2 = 1.472/1.513 = 0.973
⇒ Pt = ((1atm)(0.03)) + ((6atm)(0.973))
⇒ Pt = 5.868 atm
