A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
vovikov84 [41]
<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

The image below shows what scientific process?
lana66690 [7]

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.
