Answer:
C) the energy transferred between objects t different temperatures
Answer:
Final volume = V₂ = 8.2L
Explanation:
Given data:
Initial volume = 12.3 L
Initial pressure = 40.0 mmHg
Final volume = ?
Final pressure = 60.0 mmHg
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
40.0 mmHg × 12.3 L = 60.0 mmHg × V₂
V₂ = 40.0 mmHg × 12.3 L / 60.0 mmHg
V₂ = 492 mmHg. L / 60.0 mmHg
V₂ = 8.2L
They will ALWAYS equal the mass of the purple liquid, so answer is B
