<h3>
Answer:</h3>
5.6 L
<h3>
Explanation:</h3>
We are given;
- Initial volume, V1 = 3.5 L
- Initial pressure, P1 = 0.8 atm
- Final pressure, P2 = 0.5 atm
We are required to calculate the final volume;
- According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
- That is; P α 1/V
- Mathematically, P=k/V
- At two different pressure and volume;
P1V1 = P2V2
In this case;
Rearranging the formula;
V2 = P1V1 ÷ P2
= (0.8 atm × 3.5 L) ÷ 0.5 atm
= 5.6 L
Therefore, the resulting volume is 5.6 L

Physical change because water is not a gas or change . you can see through it.
Answer:
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 <em>wrong</em>. Oxidation is the chemical reaction of a substance with oxygen
. The splitting of a rock is a physical change.
2. is <em>wrong.</em> A landslide is the movement of ground down a slope.
3. is <em>wrong</em>. An alluvial fan is a triangle-shaped mass of sediment that a river deposits when its flow is suddenly slowed.
