Answer:
Gas
Increase the pressure
Explanation:
Let's refer to the attached phase diagram for CO₂ (not to scale).
<em>At -57 °C and 1 atm, carbon dioxide is in which phase?</em>
If we look at the intersection between -57°C and 1 atm, we can see that CO₂ is in the gas phase.
<em>At 10°C and 2 atm carbon dioxide is in the gas phase. From these conditions, how could the gaseous CO₂ be converted into liquid CO₂?</em>
Since at 10°C and 2 atm carbon dioxide is below the triple point, the only way to convert it into liquid is by increasing the pressure (moving up in the vertical direction).
Answer:
V₂ = 0.4 L
Explanation:
<u>Data:</u>
- P₁ (initial pressure) = 500 torr
- V₁ (initial volume) = 0.5 L
- P₂ (final pressure) = 700 torr
<u>Wanted:</u>
- V₂ (final volume)
<u>Equation:</u>
- P₁V₁ = P₂V₂ → V₂ = P₁V₁ / P₂
<u>Solution:</u>
- V₂ =
= 0.3571 L or 0.4 L
